실험 절차

If the procedure described in Preparation LXXXIII is followed starting from 2 g (16.8.10-3 mol) of 2-hydroxybenzonitrile, 4.4 g (25.1.10-3 mol) of silver imidazolate, 6.5 g (18.3.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide and 4.6 g (33.6.10-3 mol) of zinc chloride in 80 ml of methylene chloride, 1.32 g (yield: 20%) of the expected product are obtained after purification by chromatography on silica gel using a toluene/ethyl acetate mixture (6/1 v/v) as the eluent, and precipitation in ether.
