3-methyl-3-oxetanemethanol (100 g, 0.98 mol) was dissolved in 250 mL methylene chloride, and a 35% solution of sodium hydroxide (143.60 g, 1.08 mol)was added, and the reaction was cooled to 0° C. A solution of p-toluenesulfonyl chloride was added (186.67 g, 0.98 mol) in 375 mL methylene chloride was added over 1 hour. A white precipitate formed immediately. The reaction was stirred for 10 additional hours. 1000 mL of water was added. The dichloromethane solution layer was then removed, and dried with sodium sulfate, and the solvent was removed. Yield: 217.77 grams of 3-methyl-3-tosylmethyloxetane as white crystals, 87%.
