Hydrochloric Acid → N-(3,5-dimethylphenyl)-2-(hydroxyimino)acetamide

Participants

Reaction Steps

To a solution of chloral hydrate (14.1 g, 85.24 mM) and sodium sulfate (88.2g, 7.53 eq.) in 270 mL of water was added a solution of 3,5-dimethylaniline in a solution of concentrated HCl (16 mL) and water (51 mL), whereupon an off-white precipitate formed. The mixture was stirred for 10 min prior to adding an aqueous solution of hydroxylamine hydrochloride (17.4 g, 250 mM) in water (50 mL) and then heated at reflux for 10 min during which time the solids dissolved and a tan precipitate formed. The mixture was cooled and filtered, and the collected solids were air dried to yield the title compound (15.0 g, 95%).
