الإجراء التجريبي

If the procedure described in Preparation I is followed starting from 9.70 g (72.10-3 mol) of 2-mercaptobenzonitrile, 19.45 g (77.10-3 mol) of mercuric cyanide, Hg(CN)2, and 27.4 g (77.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide, 14.7 g (yield: 50%) of the expected product are obtained.
