Reaction Steps

A solution of cyclohexanecarbonyl chloride (118 μL, 0.880 mmol) in chloroform (0.25 mL) was added to a mixed solution of 4-amino-1-(3-chloro-benzenesulfonyl)-piperidine-4-carbonitrile (120 mg, 0.400 mmol) in chloroform (1.25 mL) and a saturated aqueous sodium carbonate solution (1.25 mL), and the mixture was vigorously stirred at room temperature for 16 hours. Cyclohexanecarbonyl chloride (51 μL) was further added and the mixture was stirred for 2.5 hours. The organic layer and the aqueous layer were then separated, and the aqueous layer was further extracted with chloroform. The organic layers were combined, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was washed with n-hexane to give cyclohexanecarboxylic[1-(3-chloro-benzenesulfonyl)-4-cyano-piperidin-4-yl]-amide as a white solid. This was used in the next step without further purification.
