Participants

Procedure

Methane sulphonyl chloride (0.16 gm, 1.1 mmol) and triethylamine (0.26 gm, 2.6 mmol) were added to a solution of [3-(benzyloxy)cyclobutyl]methanol (0.25 gm, 1.3 mmol) (step a) in dichloromethane at 0° C. and the reaction mixture was stirred at room temperature for about 2 hours. It was diluted with dichloromethane, washed with water and brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to get the title compound.
