Reaction Steps

To a 100 mL round-bottomed flask was added 4-aminobenzenethiol (4.9 g, 39.1 mmol) and potassium carbonate (9.72 g, 70.3 mmol) in dimethylformamide (20 ml). tert-Butyl 4-(tosyloxy)piperidine-1-carboxylate (5 g, 14.07 mmol) was added and the reaction was stirred in a sealed flask at 70° C. for 20 hours. The mixture was cooled and filtered through a plug of silica gel with dichloromethane. The filtrate was concentrated under vacuum and chromatographed to give the title compound.
