Procedure
A suspension of 25 g. (0.070 mole) of 2,3-dibromo-6,11-dihydro-5H-pyrrolo[2,1-b][3]benzazepin-11-one in 200 ml. ethanol containing 25 ml. of triethylamine and 1 gm. of 10% Pd on charcoal was hydrogenated under 3 atmospheres of hydrogen to yield 6,11-dihydro-5H-pyrrolo[2,1-b][3]benzazepin-11-one, m.p. 54°-55° C. after removal of catalyst, recrystallization from petroleum ether and drying under vacuum. The same compound is also obtained by hydrogenolysis of the 2,3-dichloro ketone and the 1,2,3-tribromoketone.
