Participants

Reaction Steps

A mixture of 2-(1-imidazolylmethyl)-3-methylbenzo[b]thiophene-6-carbonitrile (0.40 g), sodium hydroxide (0.20 g), ethanol (2 ml) and water (20 ml) was heated under reflux for 24 hours. The solution was evaporated and the residue was dissolved in water and the solution was acidified with acetic acid. The solid was filtered off and purified by redissolving the dilute sodium hydroxide solution, filtering and acidifying the filtrate with acetic acid. The solid was filtered off, washed with water and dried to give 2-(1-imidazolylmethyl)-3-methylbenzo[b]thiophene-6-carboxylic acid (0.35 g), m.p. 254°-255°.
