Reaction Steps
2.10 g of 1,6-bis-O-(4-carboxy-phenyl)-D-mannitol were stirred at room temperature for 20 hours in 30 ml of pyridine with 5.1 ml of acetic anhydride. The reaction mixture was worked up extractively with ice-water and methylene chloride. The organic phase was dried over magnesium sulfate, filtered and concentrated. The residue was recrystallized from methanol and methylene chloride. There was obtained 2,3,4,5-tetra-O-acetyl-1,6-bis-O-(4-carboxy-phenyl)-D-mannitol, MS: m/z 589 ([M-H]-).
