実験手順

A stirred mixture of 3-trifluoromethylbenzaldehyde (3.48 g), 1,3-cyclohexanedione (4.49 g), ammonium acetate (2.31 g) and ethanol (40 mL) was refluxed for 18 hours. The mixture was cooled and the yellow needles were collected, washed with water and dried in vacuo to give the title compound (6.38 g); mp >300 C; NMR: 1.7-2.0 (m,4), 2.19-2.25 (m,4), 2.50-2.56 (m,4), 4.98 (s,1), 7.41 (s,3), 7.48 (s,1), 9.48 (s,1); MS: m/z=362(M+1). Found for C20H18F3NO2 : C, 66.44; H, 5.00; N, 3.80.
