Procedure

To a −78° C. hazy solution under a nitrogen atmosphere of racemic 2-piperidinemethanol (0.576 g, 5.00 mmol) and triethylamine (1.42 mL, 10.0 mmol) in anhydrous dichloromethane (30 mL) was added a solution of sulfuryl chloride (0.41 mL, 5.06 mmol) in anhydrous dichloromethane (30 mL) and the reaction was stirred for around 18 h from −78° C. to ambient temperature. The clear, yellow solution was washed with 1.0N HCl (2×25 mL) and brine (25 mL), dried over Na2SO4, concentrated in vacuo to a dark yellow oil, and purified by flash column chromatography (silica gel, ether) to afford the title product as a clear yellow oil (0.342 g, 39%). The proton NMR was identical to the desired product in procedure A, step 2.
