Participants

Reaction Steps

A mixture of 4-cyanobenzenesulfonyl chloride (0.51 g, 2.5 mmol) and piperidine (0.60 mL, 517 mg, 6.04 mmol) in 10 mL methylene chloride was stirred overnight at ambient temperature. The organic layer was washed successively with water, 5% HCl and brine, dried (Na2SO4) and concentrated. The resulting white solid (0.61 g, 96%) was used with no further purification.
