Reaction Steps

2-Trityloxymethyl-1,4-butanediol diacetate (60.90 g, 0.136 mol) was dissolved in acetic acid (320 ml) at 100° C. and water, (80 ml) was added. The solution was kept at 100° C. for 15 min, evaporated in vacuum to small volume and cooled to 0° C. The precipitate was filtered off and washed with cold ethyl acetate to give 26.44 g (theory 35.51 g) of tritylalcohol. The combined filtrate was evaporated to small volume. The compound was purified on a silica gel column (500 g SiO2); eluent 0-2700 ml ethyl acetate+n-hexane (1+1), 2700-3740 ml ethyl acetate+n-hexane (2+1), then neat ethyl acetate. The fractions 2540-4800 ml were evaporated to give 14.20 g (51%) of pure 4-acetoxy-2-hydroxy-methylbutyl acetate. TLC on silica (ethyl acetate+n-hexane 1+1): Rf 0.30.
