Water → 2-[4-(2-Hydroxyiminocyclohexan-1-ylmethyl)phenyl]propionic Acid

Participants

Reaction Steps

A solution of 1.3 g of 2-[4-(2-oxocyclohexan-1-ylmethyl)phenyl]propionic acid, 0.33 g of hydroxylamine hydrochloride and 1.6 g of sodium acetate trihydrate in 85% ethanol was heated with stirring at 70°-75° C. for 2 hours, and the mixture was poured into 100 ml of water and extracted with ether. The extract was washed with water, dried over anhydrous sodium sulfate, and the solvent removed by distillation to give 1.4 g of the desired compound, which by recrystallization from a mixture of ethyl acetate and n-hexane afforded colorless prisms, m.p. 143°-150.5° C.
