To a solution of potassium di-tert-butylphosphate (2.45 g, 9.51 mmol), sodium bicarbonate (3.19 g, 38.0 mmol) and tetrabutylammonium hydrogen sulfate (340.2 mg, 0.972 mmol) in water (80 mL), was added methylene chloride (50 mL). The mixture was cooled to 0° C. and stirred vigorously under argon for 10 min. Chloromethyl chlorosulfate (1.92 g, 1.2 mL, 11.6 mmol) in methylene chloride (30 mL) was added slowly and the reaction was stirred at room temperature overnight. The organic layer was separated, washed with brine and dried over anhydrous sodium sulfate and concentrated to give di-tert-butyl chloromethyl phosphate as a colorless oil (1.46 g, 59% yield).
