참여 물질

반응 단계

2-(3,4-dimethyl-benzoyl)-3-(4-trifluoromethyl-phenylamino)-acrylic acid methyl ester 2c (151 mg, 0.40 mmol) was refluxed in 5 mL of nitrobenzene for 3 h, then cooled down and to it was added 10 mL of hexane. The crude product precipitated out of solution and was isolated by filtration. The crude product was washed with hexane to give 115 mg of 3-(3,4-dimethyl-benzoyl)-6-trifluoromethyl-1H-quinolin-4-one as off-white crystals 3b: LC-MSD, m/z for C19H14F3NO2, [M+H]+=346.4,; HPLC retention time: 2.3 min.
