Dichloromethane → (1-Cyano-3-methylenecyclobutyl)methyl methanesulfonate

Participants

Reaction Steps

To a mixture of 1-(hydroxymethyl)-3-methylenecyclobutanecarbonitrile (0.756 g, 0.00614 mol) in methylene chloride (20 mL, 0.3 mol) was added triethylamine (1.28 mL, 0.00921 mol) followed by methanesulfonyl chloride (0.594 mL, 0.00767 mol) at 0° C. The reaction was stirred at rt for 1 h, quenched with water, and extracted with dichloromethane. The combined organic layers were washed with water, brine, and then dried over magnesium sulfate and evaporated to dryness. The residue was used directly in next step.
