Participants

Reaction Steps

A solution of (3R and 3S)-3-[4-(3-hydroxypropyl)phenoxy]-1-[4-(tert-butoxycarbonyl)phenoxy]-2-butanone (0.092 g, 0.22 mmol) in dry dichloromethane (5 ml) was cooled to 0° C. and treated with triethylamine (0.07 ml, 0.5 mmol) followed by methanesulfonyl chloride (0.03 ml, 0.39 mmol). After 45 minutes at 0° C., the reaction mixture was quenched by addition of ethyl acetate (100 ml) and water. The organic phase was washed with saturated sodium bicarbonate, brine and dried (magnesium sulfate). Evaporation and chromatography of the residue on silica gel (elution toluene and ethyl acetate, 9:1) gave 0.090 g (82%) of the title material as an oil.
