Procedure

A procedure similar to that described in Preparation 12 was repeated, except that 4.92 g of benzyloxymethyloxirane (prepared as described in Preparation 46), 160 ml of an 8:1 by volume mixture of methanol and water, 9.75 g of sodium azide and 40 ml of methyl formate were used, to give 5.7 g of the title compound having an Rf value of 0.22 (on silica gel thin layer chromatography, using a 1:5 by volume mixture of ethyl acetate and hexane as the developing solvent) as a pale yellow oil.
