実験手順
A procedure similar to that described in Preparation 11 was repeated, except that 3.45 g of 1(R)-(3-chlorophenoxymethyl)-2-(2-t-butyldimethylsilyloxy-1(R)-methylethylamino)ethanol (prepared as described in Preparation 42), 1.78 g of N,N'-carbonyldiimidazole and 30 ml of anhydrous dimethylformamide were used, to give 3.52 g of the title compound having an Rf value of 0.74 (on silica gel thin layer chromatography, using a 1:1 by volume mixture of ethyl acetate and hexane as the developing solvent) and having [α]D =-53.3° (methanol, c=1.020).
