If the procedure described in Preparation LXXXIV is followed starting from 1.36 g (3.3.10-3 mol) of 3-acetylphenyl 2,3,4-tri-O-acetyl-5-thio-β-D-xylopyranoside and 0.2 ml of a solution of sodium methylate in methanol (8% w/v of Na), reacted in 50 ml of methanol for 30 min, 0.8 g (yield: 85%) of the expected product is obtained after crystallization from an ethanol/ether mixture.
