Hydrochloric Acid → (2E)-2-hydroxyimino-2-(2-phenoxyphenyl)acetamide

Participants

Reaction Steps

Conc. hydrochloric acid (1 ml) and methylene chloride (12 ml) were added to 2-(2-phenoxyphenyl)-2-hydroxyiminoacetamide (Z=at least 98%) (1.79 g, 7.0 mmol), and the mixture was stirred at room temperature for 12 hours. After stirring, water (20 ml) and toluene (20 ml) were added. The resulting crystals were separated by filtration and dried to give (E)-2-(2-phenoxyphenyl)-2-hydroxyiminoacetamide (1.70 g, Yield: 95.0%) as colorless crystals.
