Participants

Reaction Steps

Hydroxylamine hydrochloride (0.1 g) was added to a stirred solution of 1-[4-chloro-2-(N-methylacetamido)phenyl]-3-cyclopropyl-2-dimethylaminomethylenepropane-1,3-dione (0.32 g) in ethanol. The mixture was stirred for 0.75 hours and evaporated to dryness. Water was added to the residue, which was extracted (dichloromethane). The extract was dried (magnesium sulphate) and evaporated to give an oil. This was purified by chromatography eluting with ethyl acetate/dichloromethane (1:8) to give 4-[4-chloro-2-(N-methylacetamido)benzoyl]-5-cyclopropylisoxazole, (compound number 1, 0.12 g), m.p. 106.5°-107.5° C., as a white solid.
