Abstract:Ethyl 4-(3-chloro-4-methoxybenzyl) amino-2-(methylthio) pyrimidine-5-carboxylate (7) was prepared from 4-(3-chloro-4-methoxybenzylamino)-2-hydroxypyrimidine-5-carboxylate(2) by oxone oxidation reaction in acetonitrile. 4-(3-chloro-4-methoxybenzylamino)-2-hydroxypyrimidine-5-carboxylic acid(8) was obtained by hydrolysis of ethyl 4-(3-chloro-4-methoxybenzylamino)-2-hydroxypyrimidine-5-carboxyate (7) by alkali hydrolysis. 4-(3-chloro-4-methoxybenzylamino)-2-hydroxypyrimidine-5-carboxylic acid(8) reacted with thionyl chloride to form acyl chloride and reacted with 2-aminomethyl pyrimidine methanesulfonate to give 4-(3-chloro-4-methoxybenzylamino)-2-hydroxy-N-((pyrimidine-2-yl)methyl) pyrimidine-5-formamide(1) with a total yield of 7.66%. The structure of the synthetic impurity was characterized. |
Key words:Avanafil; oxidation; impurity; characterization |
