반응 단계
If the procedure described in Preparation LXXXIII is followed starting from 3.45 g (25.3.10-3 mol) of 1-(2-hydroxyphenyl)ethanone, 6 g (16.9.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-D-xylopyranosyl bromide, 3 g (17.10-3 mol) of silver imidazolate and 4.6 g (33.7.10-3 mol) of zinc chloride in 90 ml of methylene chloride and 30 ml of acetonitrile, 0.92 g (yield: 13.5%) of the expected product is obtained after purification by chromatography on silica gel using a toluene/ethyl acetate mixture (6/1 v/v) as the eluent, and crystallization from ether.
