The methods for preparing Diethyl 4 - bromo - 2,6 - pyridinedicarboxylate (diethyl 4 - bromo - 2,6 - pyridine dicarboxylate) are as follows.
First, pyridine is used as the starting material. Pyridine is brominated first. Usually, liquid bromine can be used in a suitable organic solvent such as dichloromethane under a suitable catalyst such as iron powder, and the low temperature conditions can be controlled so that the bromine atom selectively replaces the hydrogen atom at the 4th position on the pyridine ring to obtain 4-bromopyridine. Then, 4-bromopyridine is reacted with corresponding carboxylating reagents, such as carbon dioxide, under high pressure and a Grignard reagent system initiated by suitable catalysts such as magnesium metal, in ether solvents, and carboxyl groups are introduced at the 2,6 positions of the pyridine ring, and then esterified with ethanol under the catalysis of concentrated sulfuric acid to obtain the target product.
Second, 2,6-dimethylpyridine can also be used as a starting material. First, bromine is used in the presence of light or an initiator to bromide methyl to generate 2,6-bis (bromomethyl) pyridine. Subsequently, bromomethyl is oxidized to carboxyl groups through a mild oxidation step, such as the use of a mild oxidizing agent such as manganese dioxide and sulfuric acid system, to obtain 2,6-pyridinedicarboxylic This diacid is then reacted with a brominating agent such as phosphorus tribromide, so that the 4-position hydrogen of the pyridine ring is replaced by bromine, and finally esterified with ethanol to complete the synthesis of the target product.
Third, the cyclization reaction is carried out with suitable heterocyclic compounds as raw materials. For example, select an open-chain compound containing nitrogen, oxygen and suitable substituents, and carry out an intramolecular cyclization reaction in a high-temperature organic solvent in the presence of suitable shrinking agents and catalysts to construct a pyridine ring. At the same time, bromine atoms and ethyl groups are introduced in the reaction process or subsequent steps to obtain Diethyl 4-bromo-2,6-pyridinedicarboxylate.
