To prepare tert - butyl 2 - (methylamino) pyridine - 3 - carboxylate, it is often done by number method.
First, the tert-butyl 2 - halopyridine - 3 - carboxylate is reacted with methylamine. Among them, the tert-butyl 2 - halopyridine - 3 - carboxylate can be 2 - chloropyridine - 3 - tert-butyl carboxylate or 2 - bromopyridine - 3 - tert-butyl carboxylate. In appropriate solvents, such as N, N-dimethylformamide (DMF), acetonitrile, etc., add acid binding agents, such as potassium carbonate, sodium carbonate, etc., and control the temperature to make the two react. The halogen atom has high activity and can be substituted with the amino nucleophilic of methylamine to obtain the target product. For example, take an appropriate amount of tert-butyl 2-chloropyridine-3-carboxylate, dissolve it into DMF, add potassium carbonate, stir it, and slowly drop the alcohol solution of methylamine. When the reaction number is at a certain temperature, after post-treatment, such as extraction, column chromatography, etc., tert-butyl 2 - (methylamino) pyridine-3 - carboxylate can be obtained
Second, react with iodomethane with tert-butyl 2-aminopyridine-3-carboxylate. The amino group of tert-butyl 2-aminopyridine-3-carboxylate can be methylated with iodomethane. The reaction is promoted by adding a base, such as triethylamine, in a suitable organic solvent, such as dichloromethane. The methyl group of iodomethane is electrophilic and interacts with the amino group. Dissolve 2-aminopyridine-3-carboxylate into dichloromethane, add triethylamine, drop into iodomethane, react under certain conditions, and complete the reaction. After washing, drying, distillation and other operations, the target product is obtained.
Third, pyridine-2,3-dicarboxylic anhydride is used as the starting material. First, pyridine-2,3-dicarboxylic anhydride reacts with tert-butanol to obtain 2-tert-butoxycarbonyl pyridine-3-carboxylic acid, and then reacts with methylamine. Pyridine-2,3-dicarboxylic anhydride reacts with tert-butanol under acid catalysis, such as p-toluenesulfonic acid, and reacts with heat to form 2-tert-butoxycarbonyl pyridine-3-carboxylic acid. After reacting with methylamine in a suitable solvent, such as ethanol, at a certain temperature to obtain tert-butyl 2 - (methylamino) pyridine - 3 - carboxylate, the purity of the product can be improved by separation and purification.

Tert-butyl 2 - (methylamino) pyridine-3 - carboxylic acid ester, this is an organic compound. Its physical properties are quite important and are related to many practical applications.
First, the appearance, at room temperature and pressure, is mostly colorless to light yellow liquid form, uniform texture and transparent, and the appearance has a flowing state. This appearance feature is convenient for users to judge whether it is pure or not and whether there are obvious impurities mixed in during preliminary observation.
Besides, the boiling point is about a specific temperature range. Due to factors such as intermolecular forces and structures, its boiling point value is specific. This boiling point characteristic is of great significance when separating and purifying the compound. By precisely controlling the temperature, the substance can be separated from the mixture in a gaseous state, and then condensed back to the liquid state to achieve purification.
The melting point also has a specific value. The melting point is the key indicator between the solid and liquid state transitions. If the compound has high purity, the melting point range is relatively narrow; if it contains impurities, the melting point may decrease and the melting range becomes wider. This allows the purity of the compound to be detected.
In terms of solubility, it exhibits good solubility in common organic solvents such as ethanol and dichloromethane. This is due to the interaction between its molecular structure and solvent molecules, such as van der Waals force, hydrogen bonding, etc. This solubility is extremely critical in organic synthesis reactions, allowing the reactants to be fully contacted and improving the reaction rate and yield. In water, the solubility is poor due to the poor matching of molecular polarity with water molecules.
Density is also an important physical property. Compared with water, there is a specific density value. This allows for the effective separation of the compound from other liquids based on density differences when it comes to liquid-liquid separation operations. For example, in the post-treatment stage of the reaction, if the product is immiscible with water and has different densities, a preliminary separation can be achieved by liquid separation operations.
