Abstract The best yield for the synthesis of the title compound was obtained by nucleophilic displacement of the 4- O -triflyl group in methyl tri -O- benzyl -4-O- triflyl -β- d - galactopyranoside by 2,3,4,6- tetra -O- acetyl -1-S- acetyl-1-thio -β- d - glucopyranose in HMPA in the presence of diethylamine. Under these conditions, the formation of unsaturated side products was decreased.
