PURPOSE:To obtain the titled compound useful as an intermediate for a trifluoromethyl group-containing compound useful as drugs, agricultural chemicals and other uses, by subjecting a trifluoromethyl group-containing nitrogen-containing heterocyclic compound and an olefin to photo-addition reaction. CONSTITUTION:A trifluoromethyl group-containing nitrogen-containing heterocyclic compound [e.g. trifluoromethylquinoxalin-2-(1H)-one, etc.] shown by formula I (A is aromatic nucleus bonded at the o-position; Z is O or N(R) (R is H or monofunctional organic group] is reacted with an olefin (e.g. methyl methacrylate, etc.) shown by formula II (R<1> and R<2> are H, halogen, nitrile, alkyl, alkoxy, alkoxycarbonyl, etc.) in a nonreactive solvent or a reactive solvent in the presence of light rays to give a nitrogen-containing heterocyclic derivative (e.g. compound wherein A is o-phenylene, Z is NH, R<1> is CO2Me and R<2> is Me) shown by formula III or formula IV (R<3>-R<5> are R<1>, R<1> residue, R<2>, R<2> residue, etc.).
