実験手順
To a stirred solution of 1-(4-fluorophenyl)-2-phenylethan-1,2-dione (1.0 g) in acetic acid (25 ml) and acetic anhydride (3 ml) containing ammonium acetate (5.0 g) was added isobutyraldehyde (0.5 g) and the reaction mixture was warmed to 110° for 2 h. The mixture was poured into aqueous ammonium hydroxide at 0° and the deposited solid was collected by filtration, then washed sequentially with ether and water then dried in vacuo to afford the title compound (1.09 g), λmax (EtOH) 252 (9550) and 287.8 nm (ε11,870).
