Procedure
2-Propanethiol (0.8 mL, 8 mmol) is added to a solution of 3-chloro-5-(phenylmethoxy)benzo[b]thiophene-2-carboxamide (1.0 g, 3 mmol) and diazabicycloundecene (DBU) (2.6 mL, 17 mmol) in 10 mL of DMF and the mixture is warmed to 55° C. for 1 hour. The reaction mixture is allowed to cool and then poured into water and stirred. After 1 hour, the precipitate is filtered off, washed with water, and dried to provide 3-[(1-methylethyl)thio]-5-(phenylmethoxy)benzo[b]thiophene-2-carboxamide in 98% yield; mp=150°-152° C.
