A facile synthesis of the title compound (9) was achieved. Tritylation of 1, 6-anhydro-β-N-acetylglucosamine (4) with 3 molar equivalents of trityl chloride in pyridine at 85-90°C for 24 h afforded the corresponding 4-O-trityl ether (5) and 3-O-trityl ether (6) in 66.9 and 8.3% yields, respectively, after column chromatography. Benzylation of 5 followed by detritylation provided 9 via 3 steps from 4 in ca. 47% yield. Preparation of 2-acetamido-1, 6-anhydro-4-O-benzyl-2-deoxy-β-D-glucopyranose (10) from 6 was also carried out.
