実験手順

If the procedure described in Preparation IV is followed starting from 10.3 g (74.1.10-3 mol) of 3-mercaptobenzonitrile, 28.94 g (81.5.10-3 mol) of 2,3,4-tri-O-acetyl-5-thio-α-D-xylopyranosyl bromide and 6.05 g (74.3.10-3 mol) of zinc oxide (ZnO), 9.6 g (yield: 31%) of the expected product are obtained.
