Procedure

Azetidin-3-ol (3.3 g) and DIPEA (20 mL) are dissolved in dry tetrahydrofuran (40 mL). After 30 min the reaction mixture is cooled to 0° C. and methanesulfonyl chloride (10.9 g) is added dropwise. After stirring for 2 hours at ambient temperature, the mixture is concentrated under vacuum, partitioned between ethyl acetate and water. The organic phase is dried (MgSO4) and concentrated. Chromatography of the residue on silica gel (cyclohexane/ethyl acetate 70:30) gives the title compound. Yield: 5 g.
