反応手順
If the procedure described in Preparation I is followed starting from 4.8 g (258.10-3 mol) of 3,5-dicyano-2-mercaptobenzonitrile (Example 17a), 9.71 g (258.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide and 6.57 g (8.6.10-3 mol) of mercuric cyanide (Hg(CN)2), 2 g (yield: 17%) of the expected product are obtained after crystallization from ether.
