Procedure

(Step 1) A mixture of 5-chloro-2-fluorobenzonitrile (6.0 g) and sodium propane-2-thiolate (4.16 g) was stirred in N,N-dimethylformamide (30 ml) at room temperature for 18 hr. The reaction solution was treated with 1N hydrochloric acid, and extracted with ethyl acetate. The extract was washed successively with aqueous sodium hydrogen carbonate solution and saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 5-chloro-2-[(1-methylethyl)sulfanyl]benzonitrile (7.26 g).
