Reaction Steps

A solution of ethanesulfonic acid isopropyl ester (1.0 g, 6.6 mmol) in tetrahydrofuran (15 mL) was cooled to −78° C., and n-butyllithium (1.57 M, 4.6 mL, 7.2 mmol) was added. After stirring at −78° C. for 20 minutes, diethyl chlorophosphate (0.52 mL, 3.6 mmol) was added to the reaction mixture, and the mixture was further stirred for 30 minutes. 1N Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over sodium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=40/60) to give the title compound (0.61 g, 2.1 mmol, 58%).
