Imidazole → Benzyl N-[2-t-Butyldimethylsilyloxy-1(S)-methylethyl]carbamate

Participants

Reaction Steps

A procedure similar to that described in Preparation 8 was repeated, except that 7.00 g of (S)-2-benzyloxycarbonylaminopropanol (prepared as described in Preparation 31), 6.03 g of t-butyldimethylsilyl chloride, 5.45 g of imidazole and 100 ml of anhydrous dimethylformamide were used, to give 10.52 g of the title compound having an Rf value of 0.48 (on silica gel thin layer chromatography, using a 1:7 by volume mixture of ethyl acetate and hexane as the developing solvent).
