Participants

Reaction Steps

To a solution of 1.30 g (3.20 mmol) 2-(3,4-dichloro-phenyl)-N-[2-(3-methoxy-4-prop-2-ynyloxy-phenyl)-ethyl]-2-oxo-acetamide in 7.0 ml ethanol, 0.52 ml pyridine (0.64 mmol) and 0.33 g (3.98 mmol) O-methylhydroxylamine hydrochloride are added. The solution is heated at +80° C. for 4 hours. After evaporation of the solvent, the residue is submitted to flash-chromatography to yield the 2-(3,4-dichloro-phenyl)-2-methoxyimino-N-[2-(3-methoxy-4-prop-2-ynyloxy-phenyl)-ethyl]-acetamide as a white solid (m.p. 107-108° C.)
