Procedure

Here, 3-(7,8-dimethoxy-1,3,4,5-tetrahydro-2H-3-benzazepin-2-on-3-yl)-1-chloropropane (10 g, 0.0336 mol) is heated to 130° C. for 3 hours with 2-(3,4-dimethoxyphenylamino)-ethylamine (13 g, 0.066 mol). After cooling, the reaction mixture is distributed between sodium hydroxide solution and methylene chloride. The organic phase is separated, dried over sodium sulfate and concentrated. The residue is chromatographed on silica gel (eluant: methylene chloride/methanol/conc. ammonia: 90/10/0.25). The product thus obtained is converted into the dihydrochloride in the usual way.
