9, 2-[2-(5-Bromo-2-methoxy-phenyl)-ethyl]-3-chloro-thiobenzamide. As shown in Scheme 9, hydrogen sulfide gas was bubbled into a solution of 2.75 g (7.8 mmol) of 2-[2-(5-Bromo-2-methoxy-phenyl)-ethyl]-3-chloro-benzonitrile in 20 mL of ethanol and triethylamine (5:4 v/v) for 10 minutes. The solution was then heated to 80° C. in a sealed pressure tube for 5 hours. The reaction mixture was diluted with water and extracted with ethyl acetate twice. The organic extracts were washed with brine, dried (MgSO4), filtered and evaporated to give 3.0 g of crude product which was used directly in the next step.
