Reaktionsschritte
If the procedure described in Preparation I is followed starting from 2.3 g (10.9.10-3 mol) of 4-(4-mercaptophenyl)benzonitrile, 4.26 g (11.9.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide and 2.75 g (10.9.10-3 mol) of mercuric cyanide (Hg(CN)2), 0.540 g (yield: 10%) of the expected product is obtained after purification by flash chromatography using methylene chloride as the eluent.
