Procedure

To a solution of 1-(propane-1-sulfonyl)-azetidin-3-ol (236 mg, 1.317 mmol) in pyridine was added drop wise methane sulfonyl chloride (205 μl, 2.63 mmol) at 0° C. The mixture was allowed to warm up to room temperature and was stirred for 3 h. Dichloromethane was added. The mixture was subsequently washed with water, saturated NaHCO3 and brine, dried (MgSO4), and filtrated. The solvent was evaporated to obtain 293 mg of crude product which was used without further purification.
