Participants

Reaction Steps

A mixture of 4-hydroxy-4-methyl-2-pentanone (10.0 g, 85.7 mmole) and hydroxylamine hydrochloride (22.17 g, 343 mmole) in 90 ml of water was stirred vigorously at room temperature. To this solution was added slowly over a period of an hour solid sodium bicarbonate (26.8 g, 343 mmole). After 3 hours the reaction mixture was extracted with ethyl acetate (3×, 100 ml), dried (MgSO4) and evaporated under reduced pressure, to give the product as an oil. Yield 11.2 g
