Procedure

This compound was prepared according to the procedure used to synthesize the compound of Example 11. A mixture of 1.9 g (0.01 mole) of 1,1'-carbonyldiimidazole, 1.0 g (0.01 mole) of unsym-dimethylethylenediamine, and 2.0 g (0.1 mole) of 1-(4-methylphenyl)piperazine in a total volume of 100 ml of tetrahydrofuran gave an oil which solidified. The solid was triturated with petroleum ether (30°-60° C.) to give 1.5 g (47%) of the title compound as a white solid, m.p. 85°-88° C.
