Abstract:2-hydroxymethyl-4-methoxy-3, 5-dimethylpyridine, an intermediate of Omprazole and Esomprazole, was synthesized from 2,3,5-trimethylpyridine by N-oxidation, nitration, and methoxy-lation to give the 4-methoxy-3, 5-dimethylpyridine-N-oxide, which was then treated with acetic anhydride and followed by hydrolysis using dilute hydrochloric acid as hydrolytic reagent to give the title compound. The overall yield reached 69. 7% and the method had the advantage of mild reaction, low cost and waste.
Keywords:2  3  5-trimethylpyridine  2-hydroxymethyl-4-methoxy-3  5-dimethylpyridine  synthesis
