Example 3; 9-Bromo-7,12-dihydroindolo[3,2-d][1]-benzazepin-6(5H)-one (Compound 1.2); To a suspension of 1 H-[1]benzazepin-2,5(3H, 4H) -dione (0.247 g, 1.3 mmol) in acetic acid (5 ml) was added 4-bromophenylhydrazine hydrochloride (0.532 g, 2.3 mmol) and sodium acetate (0.195 g, 2.3 mmol) and stirred under argon. The mixture was heated at 70°C for 3 hours, then cooled and concentrated sulfuric acid (0.5 ml) added, before heating at 70°C for a further 3 hours. The slurry was poured into 10percent sodium acetate aqueous solution (20 ml) and the precipitate filtered to give the title compound as a cream solid (0.367 g, yield 79.6percent), mp > 300°C; 1 H- NMR (DMSO- d6,300 MHz) : No. (ppm) = 11.82 (s; 1 H), 10.1 (s; 1H), 7.89 (d; 1H), 7.74 (dd; 1H), 7.41-7.36 (m; 2H), 7.30-7.21 (m; 3H), 3.51 (s; 2H). |
