Participants

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-dimethylethylenediamine, and 5.8 g (0.03 mole) of 1-(4-methoxyphenyl)piperazine in a total of 200 ml of tetrahydrofuran gave an oil which solidified. After trituration with petroleum ether (30°-60° C.), the collected solid was recrystallized from cyclohexanebenzene to yield 2.2 g (24%) of the title compound as a white, crystalline solid, m.p. 79°-82° C.
