Procedure

9H-Tribenz[b,d,f]azepine (0.17 g, 0.70 mmol, prepared similarly as described by H. C. Axtell et al., J.Org.Chem. 56, 3906 (1991)) was suspended in dry toluene (5 ml). 3-Chloropropionyl chloride (0.13 g, 1.0 mmol) and triethylamine (0.1 ml) were added and the mixture was heated at reflux temperature for 1.5 hour. Saturated aqueous sodium bicarbonate (10 ml) was added, and the phases were separated. The organic phase was washed with brine (10 ml), dried (MgSO4) and concentrated in vacuo, affording 220 mg, (94%) of crude 3-chloro-1-(9H-tribenz[b,d,f]azepine-9-yl)propan-1-one as a foam.
