To a 10 mL round-bottomed flask was added tert-butyl 4-(4-aminophenylthio)piperidine-1-carboxylate (100 mg, 0.324 mmol) and triethylamine (249 μl, 1.783 mmol) in dichloromethane (3242 μl). The mixture was cooled to −78° C. and acetyl chloride (115 μl, 1.621 mmol) was added. The solution was warmed to room temperature, stirred for 1 h and then diluted with water and additional dichloromethane. The aqueous phase was extracted twice with dichloromethane and the combined organics were dried with sodium sulfate, filtered and concentrated to give the title compound.
