Procedure
To 4-(methylthio)aniline (1 mL, 8.19 mmol) in dichloromethane (20 mL) was added pyridine (2 mL, 24.6 mmol). The resulting solution was cooled to 10-15° C. and 4-chlorobenzoyl chloride (1.14 mL, 9.00 mmol) was added over 5 min. The mixture was stirred at room temperature for 90 min. The precipitate was filtered off, washed with dichloromethane, 1M aqueous sodium hydroxide solution and 1M aqueous hydrochloric acid solution to afford 2.12 g (93%) of the title compound.
