Procedure

To a solution of the product of step 1 (270 mg) in acetic acid (2.2 ml) and water (0.5 ml) were added amidosulfuric acid (67 mg) and sodium chlorite (68 mg) in water (0.1 ml), and the mixture was stirred at room temperature for 15 minutes. The reaction mixture was distilled off under reduced pressure into half volume. The residue was neutralized with 1N sodium hydroxide. The precipitation was filtered and washed with water to give the titled compound (80 mg).
