Reaction Steps

A mixture of 1.3 g (15.5 mmole) of (14bR)-2-(2-chloroethyl)-1,2,3,4,10,14b-hexahydrodibenzo[c,f]-pyrazino [1,2-a]azepine [prepared as described in step (a) above], 3.6 g of piperazine and 30 ml of toluene was header under reflux for 16 hours. At the end of this time, the mixture was cooled and water was added. Sufficient of a 10% w/v aqueous solution of acetic acid was then added to make it acidic. The aqueous layer was separated, neutralized with a 10% w/v aqueous solution of sodium hydroxide, and extracted with diethyl ether. The solvent was then removed by evaporation under reduced pressure, to give 1.38 g (yield 92%) of the title compound.
