Reaction Steps

This compound was prepared according to the procedure used to synthesize the compound of Example 11. A mixture of 4.9 g (0.03 mole) of 1,1'-carbonyldiimidazole, 2.6 g (0.03 mole) of unsym-diethylethylenediamine, and 5.9 g (0.03 mole) of 1-(2-chlorophenyl)piperazine in a total of 200 ml of tetrahydrofuran gave an oil as residue. The hydrochloride was formed in ethereal hydrogen chloride and the collected solid was recrystallized from methanol-ethyl ether to yield 3.4 g (33%) of title compound as a white solid, m.p. 185°-188° C.
