Participants

Reaction Steps

3-(4-Hydroxybut-1-yl)cyclopentene {2-cyclopentene-1-butanol} (51 g, 0.37 moles) is diluted in dimethylformamide (100 ml) and added to pyridine (38 g, 0.40 moles). The solution is stirred and methanesulfonyl chloride (46 g, 0.40 moles) is added dropwise over 10 minutes. The reaction is partitioned between hexane (500 ml) and the organic phase separated. The aqueous layer is extracted with hexane (2×500 ml) and the organic extracts combined. The solvent volume is reduced under vacuum and the residue dried over anhydrous magnesium sulfate. The solid is filtered off and the remaining solvent removed leaving a clear yellow oil. The crude product is fractionally distilled under reduced pressure leaving a clear, colorless oil (43 g, 0.27 moles), BP 40°0/0.2 mm.
