Procedure
Sodium (126 mg, 5.47 mmol) was added to abs. methanol (50 ml) and the reaction mixture was stirred for 5 min. D-glucosamine hydrochloride (1.18 g, 5.47 mmol) was added to the resulting clear solution and the reaction mixture was stirred at room temperature for another 5 min. 2-acetyl-4-nitroindane-1,3-dion (1.91 g, 8.21 mmol) was added and the reaction mixture was stirred under reflux for 5 hours. The solution was cooled and the product was filtered off. The solid was washed with MeOH (10 ml), ether (50 ml) and dried, affording 2-Deoxy-2-[1-(4-nitro-1,3-dioxoindan-2-ylidene)ethylamino]-D-glucopyranose (22) 1.10 g, 55%).
