Procedure

A suspension of 39.0 mg (41.2 μmol) of 16-({[5-(aminomethyl)-4-hydroxy-3-methoxytetrahydro-2-furanyl]oxy}{5-[2,4-dioxo-3,4-dihydro-1 (2H)-pyrimidinyl]-3,4-dihydroxytetrahydro-2-furanyl}methyl)-9-(1-hydroxy-2-methylpropyl)-6-(2-iminohexahydro-4-pyrimidinyl)-2-isopropyl-4,7,10-trioxo-3,5,8,11,15-pentaazaheptadecane-1,17-dioic acid in 2.0 ml of acetic anhydride is placed in an ultrasonic bath (Branson 1200) at room temperature for 35 minutes. Water (2 ml) and n-butanol (2 ml) are added to the reaction mixture and the volatile materials removed under reduced pressure to a residue which is suspended in 2 ml of acetone and the suspension filtered through glass wool. The desired product (the acetone insoluble product) is recovered as a white solid by dissolving in 2 ml water followed by lyophylization.
