실험 절차

To a well stirred suspension of di-tert-butyl hydrogen phosphate (4.7 g, 22.47 mmol) in water (186 ml) was added sodium bicarbonate (7.5 g, 89.52 mmol) followed by tetra-n-butylammomium hydrogen sulphate (760 mg, 2.238 mmol). The reaction mixture was stirred at room temperature for 15 min. To the reaction mixture was added dichloromethane (112 ml) at 0° C. and it was stirred for 10 min followed by the addition of chloromethyl chlorosulphate (4.4 g, 26.85 mmol) in dichloromethane (75 ml) at same temperature. The resultant mixture was vigorously stirred overnight at room temperature. The organic layer was separated, washed with brine and evaporated under reduced pressure to yield 3.04 g of product as pale yellow oil.
