Procedure

(Step 1) A 3 M aqueous solution of methyl mercaptan sodium salt (15 ml) was added to a solution of 5-chloro-2-fluorobenzonitrile (5.0 g) in DMSO (100 ml). The resulting mixture was stirred at room temperature for 2 hr. To the reaction mixture was added water (200 ml) and the resulting mixture was stirred at room temperature for 30 min. The precipitate was collected by filtration, washed with water, and dried to give 5-chloro-2-(methylsulfanyl)benzonitrile (4.6 g) as a white solid.
