الإجراء التجريبي

If the procedure described in Preparation I is followed starting from 1.8 g (10.10-3 mol) of 2trifluoromethylbenzenethiol, 2.55 g (10.10-3 mol) of mercuric cyanide (Hg(CN)2) and 3.95 g (11.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide, 1.53 g (yield: 34%) of the expected product are obtained.
