Reaktionsschritte
1,3,4,6-Tetra-O-acetyl-2-amino-2-deoxy-alpha-D-glucopyranose (151) and 3-hydroxy-4-methoxypicolinic acid were coupled together using standard coupling procedure C. To a solution of the resulting picolinamide (0.19 g, 0.38 mmol) in 6 mL of methanol was added lithium hydroxide monohydrate (0.92 mmol, 40 mg). The reaction mixture was stirred at room temperature overnight. The solution was neutralized by the addition of DOWEX® 5×8-100 acidic resin (0.5 g). The mixture was filtered and concentrated to afford the title compound (110 mg, 88%).
