Song, Weiguo published the artcileSynthesis of esomeprazole magnesium, Computed Properties of 161796-78-7, the publication is Zhongguo Yiyao Gongye Zazhi (2013), 44(8), 744-746, database is CAplus.
Esomeprazole magnesium, a proton pump inhibitor, was synthesized from 2-hydroxymethyl-3,5-dimethyl-4-nitropyridine by chlorination, condensation, asym. oxidation, methoxylation and then reacted with magnesium chloride. The overall yield was 73.6% (based on 2-hydroxymethyl-3,5-dimethyl-4-nitropyridine).
