Reaction Steps

A solution of benzoyl isocyanate (2.94g) in methylene chloride (5ml) is added to a solution of 4,5,6,7-tetrahydrobenzo[b]thiophen-4-amine is methylene chloride (50ml) under a nitrogen atmosphere. After stirring overnight at room temperature, the reaction mixture is evaporated to dryness in vacuo. The residue is then stirred in ether (100ml) and filtered to afford 1-benzoyl-3-(4,5,6,7-tetrahydrobenzo-[b]thien-4-yl)urea, m.p. 189° to 194° C.
