Procedure

To the stirred solution of 1.3 g of 1,3,4,14b-tetrahydro-2H,10H-pyrazino[1,2-a]pyrrolo[2,1-c][1,4]benzodiazepine (Example 4) and 550 mg of triethylamine in 15 ml of tetrahydrofuran is added 765 mg of benzoyl chloride. After allowing the mixture to stir at room temperature overnight it is evaporated and the residue taken up in 100 ml of water. The mixture is extracted with diethyl ether, washed successively with water and brine, dried and evaporated, to yield 2-benzoyl-1,3,4,14b-tetrahydro-10H-pyrazino[1,2-a]pyrrolo[2,1-c][1,4]benzodiazepine melting at 137°-139° after recrystallization from isopropanol.
