Procedure

A solution of diphenyl(2,3,4-tri-O-acetyl-α-D-fucopyranosyl)-phosphate (2.0 g) in anhydrous dimethylformamide (80 mL) containing sodium azide (2.0 g) was heated to 50° C. for 2 h and processed as described in the synthesis of Compound 5, part c (Experiment 4). The product was purified by chromatography on a column of silica gel using ethyl acetate--hexane (3:8) as eluant to obtain the title compound (1.13 g).
