Participants

Reaction Steps

To a solution of 4-nitrobenzenesulfonyl chloride 40 g 0.181 mole in dichloromethane 400 ml was added over 30 mins a solution of pyridine 15 g 15.3 ml and piperidine 16.15 g 18.8 ml in dichloromethane 100 ml. The mixture was stirred at room temperature for 2 h and then washed with water, 2M hydrochloric acid and brine, dried MgSO4 and evaporated in vacuo to give 1-(4-nitro-benzenesulfonyl)-piperidine 44.5 g. 1H NMR CDCl3 7.76 (2H, d), 7.40 (2H, d), 3.21 (6H, q), 1.07 (6H, t).
