Reaction Steps

3-Cyclopentene-1-ol (0.500 g, 5.94 mmol) was stirred in DCM (95 mL). Pyridine (2.40 mL), N,N-dimethylaminopyridine (0.10 g, 1.00 mmol) and methanesulfonyl chloride (0.690 mL, 8.92 mmol) were added, and the reaction mixture was stirred at 35° C. for 4 h. N,N-Dimethylaminopyridine (0.14 g, 1.2 mmol) and methanesulfonyl chloride (0.69 mL, 8.92 mmol) were added, and the reaction was stirred overnight. TLC indicated complete conversion. The reaction mixture was cooled and concentrated. The residue was purified by silica gel chromatography, eluting with DCM, to afford the title compound as a clear oil (0.660 g, 68%).
