Procedure:
To a solution of 8-bromo-5-oxo-2,3,4,5-tetrahydro-1-benzothiepine (5.00 g) synthesized according to a known method in N,N-dimethylformamide (50 ml) were added zinc cyanide (2.28 g) and tetrakis(triphenylphosphine)palladium(0) (1.13 g) and the mixture was stirred at 80-90° C. for 1 hr. The reaction mixture was allowed to warm to room temperature and water (500 ml) and ethyl acetate (100 ml) were added. The mixture was passed through celite.
