実験手順

4.7 ml (40 mmol) of benzoyl chloride were added to a solution of 5.34 g (30 mmol) of 2-amino-3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophene in 50 ml of pyridine. Stirring was carried out for 2 hours at 80° C. after which 150 ml of 10 mol % aqueous hydrochloric acid were added to the mixture. The solid formed was isolated in a conventional manner. Yield: 97%; mp.: 168°-170° C.
