To prepare 2-methoxy-5-methylpyridine, the following ancient method can be used.
First take an appropriate pyridine derivative as a group. This derivative needs to have a modifiable group at a specific position in the pyridine ring to prepare for the subsequent introduction of methoxy and methyl groups.
When introducing methoxy groups, it is often done by the reaction of alkoxides and halides. Choose a suitable halogenated pyridine, the position of the halogen atom should match the place where the methoxy group is to be formed. Take an alkoxide, such as sodium methoxide, and put it in a suitable solvent, such as dimethylformamide (DMF), to control its temperature, stirring rate and reaction time. Halopyridine is mixed with sodium methoxide, the halogen atom binds to the sodium in sodium methoxide, and the anion of alcohol replaces the position of the halogen atom to form the methoxylated pyridine intermediate. This reaction needs to be in an anhydrous and oxygen-free environment to prevent side reactions, and precise temperature control is required. If the temperature is too high or too low, the reaction rate and yield will be affected.
As for the introduction of methyl groups, Grignard reagents or alkylating reagents can be used. If Grignard reagents are used, methylmagnesium halide is first prepared, and magnesium chips are obtained by reacting with halomethane in anhydrous ether or tetrahydrofuran. The previously methoxylated pyridine intermediate is slowly added to a solution containing methylmagnesium halide at low temperature. The methyl negative ion of methylmagnesium halide attacks the nucleophilic position on the pyridine ring at a suitable position. After the reaction, the product is purified by conventional post-processing methods such as extraction, washing, drying, distillation or column chromatography to obtain high-purity 2-methoxy-5-methylpyridine.
Alkylation reagent method, select a suitable methylation reagent, such as iodomethane, and react in the presence of a base. The base can remove the hydrogen at a specific position on the pyridine ring to form a carbon anion. It reacts with iodomethane, and methyl substitutes hydrogen to obtain the target product. This process also requires fine regulation of reaction conditions to achieve ideal yield and purity.
