実験手順

To oxime 1c (1.25 g; 8.18 mmol) in concentrated hydrochloric acid (6.0 mL) at 0° C., was added dropwise bleach (9 mL). The reaction mixture was stirred at 0° C. for 1 h, diluted with water (20 mL) and brought to about pH=3 with saturated sodium bicarbonate. The resulting solid was collected, washed with water and dried. 2c was isolated as a white solid.
