Condensation of 2-methyl-(3,4,6-tri-O-acetyl-1,2-dideoxy-alpha-D-glucopyrano)-[2',1':4,5]-2-oxazoline with p-nitrophenyl 2,3-di-O-acetyl-beta-D-galactopyranoside (4), followed by saponification of the resulting disaccharide derivative, produced p-nitrophenyl 6-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-beta-D-galactopyranoside as a crystalline compound. Reaction of 2-methyl-[4,6-di-O-acetyl-1,2-dideoxy-3-O-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosyl)-alpha-D-glucopyrano]-[2',1':4,5]-2-oxazoline with 4 in a similar reaction-sequence provided the title trisaccharide compound.
