Versuchsvorschrift

p-Toluenesulfonyl chloride (57.2 g, 300 mmol) was dissolved in dry pyridine (400 mL) under nitrogen atmosphere. 3-methyl-3-(hydroxymethyl)oxetane (20.4 g, 200 mmol) was added slowly, and the solution was stirred for 1.5 h. Crushed ice (400 g) was then added to vigorously stirring mixture, which was allowed to stir for an additional 0.5 h. The white precipitate was then collected on Whatman filter paper #1 and washed with cold water. The product was dried under high vacuum to obtain 3-methyl-3-(toluenesulfonyl-oxymethyl)oxetane (oxetane tosylate) as a white powder of oxetane tosylate.
