Reaction Steps

Under ice-cooling, to a solution of (R)-3-(2-methoxyphenyl)propane-1,2-diol (1.62 g) and imidazole (0.92 g)in dimethylformamide was added t-butyldimethylsilyl chloride (1.36 g),and stirred for 15minutes successively. The reaction solutionwas poured into water, extracted with ethyl acetate, and dried oversodium sulfate. After the solvent was evaporated in vacuo, thegained crude product was purified by silica gel columnchromatography, and it was eluted with a mixed solvent of hexaneand ethyl acetate (7:1, v/v). The fractions containing the desiredproduct were combined and evaporated in vacuo to obtain (R)-1-t-butyldimethylsiloxy-3-(2-methoxyphenyl)-2-propanol(2.22 g).
