Benzenesulfonyl chloride → Ethyl 1-(phenylsulfonyl)piperidine-3-carboxylate

Participants

Reaction Steps

A mixture of ethyl piperidine-3-carboxylate (1.00 g, 6.36 mmol), benzenesulfonyl chloride (0.812 mL, 6.36 mmol), and triethylamine (2.66 mL, 19.1 mmol) in methylene chloride (10.0 mL) was stirred at r.t. for 2 hours. The mixture was quenched with water, then extracted with ethyl acetate. The extract was washed with 1N HCl solution, water, sat'd sodium bicarbonate solution, water, and brine, successively. Then, the extract was dried over sodium sulfate (anhydrous). After filtration, the filtrate was concentrated to yield 1.79 g (94%) of ethyl 1-(phenylsulfonyl)piperidine-3-carboxylate.
