Versuchsvorschrift
To 48 mg of N-[2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-(ethoxyimino)ethyl]-2-(trifluoromethyl)benzamide in 3 ml of acetonitrile, 1 mg of benzophenone was added, and the mixture was irradiated with light for 4 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 1:9 to 5:5) as the eluent to obtain 42 mg of the desired product as white crystals.
