A 0.552 mL (4.42 mmol) sample of phenoxycarbonylchloride in 2 mL of methylene chloride was added to a solution of 376 mg (3.68 mmol) of 3-hydroxymethyl-3-methyloxetane and 60.7 mL (5.52 mmol) of 4-methylmorpholine in 2 mL of methylene chloride cooled in an ice bath. The mixture was stirred at 0° C. for 3.5 hours. The mixture was diluted with methylene chloride, which was washed with water, dried and concentrated. The crude product was chromatographed on silica gel, eluting with 20% ethyl acetate in hexane. The solvent was removed and the product dried to afford 0.582 g of the title compound, which was taken directly to the next step.
