To 218 mg of N-[2-(3,5-dichloropyridin-2-yl)-2-(propoxyimino)ethyl]-2-(trifluoromethyl)benzamide in 3 ml of acetonitrile, 5 mg of benzophenone was added, and the mixture was irradiated with light for 48 hours in a quartz cell (manufactured by Fine, 4 clear windows for spectroscopy) using a 100 W high-pressure mercury lamp (manufactured by USHIO INC., lamp: UM-102, power supply UM-103B-B). After completion of the reaction, the solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel column chromatography using ethyl acetate-hexane (with a gradient of from 25:75 to 35:65) as the eluent to obtain 83 mg of the desired product as white crystals.
