Methanesulfonyl chloride → Tert-butyl 3-((methanesulfonyloxy)methyl)azetidine-1-carboxylate

Participants

Reaction Steps

To a solution of (1-Boc-azetidin-3-yl)-methanol (1.06 g, 5.7 mmol), TEA (1.18 mL, 8.52 mmol) in CH2Cl2 at 0° C. was added MeSO2Cl (0.53 mL, 6.82 mmol) via a syringe. The reaction was warmed to RT over 2 h and stirring was continued at RT for 2 h. The white solid formed was removed by filtration and the filtrate was washed with 25 mL of H2O. The organic phase was dried over Na2SO4, and concentrated in vacuo to afford yellow oil.
