Reaction Steps

A solution of diazomethane in methylene chloride was added to a suspension of 10.45 g of 2-ethyl-thiazole-5-carboxylic acid in 30 ml of methylene chloride until efferversence stopped and the methylene chloride was distilled. The oily residue was chromatographed over silica and was eluted with a 1:1 mixture of benzene-ethyl acetate to obtain 11.3 g of methyl 2-ethyl-thiazole-5-carboxylate.
