Procedure

A mixture of 2-(1-imidazolylmethyl)-3-methylbenzo[b]thiophene-5-carboxylic acid ethyl ester (1.0 g) and 6N hydrochloric acid (80 ml) was heated on a steam bath for 5 hours and then cooled. The solid was filtered off, dried and crystallized from ethanol ether to give 2-(1-imidazolylmethyl)-3-methylbenzo[b]thiophene-5-carboxylic acid hydrochloride (0.72 g), m.p. 298°-299° C.
