실험 절차

A mixture of N-3-[4-(2-chlorophenyl)piperazin-1-yl]propyl-N '-(3,4-ethylenedioxyphenyl)thiourea of Example 11 (1.35 g; 3 mmol), triphenylphosphin (1.02 g; 3.9 mmol), carbon tetrachloride (0.56 ml), triethylamine (0.3 g; 3 mmol) and methylene chloride (15 ml) Was stirred at reflux for 3 h and at 400° C. for 16 h. The reaction mixture was concentrated in vacuo and then taken up in petroleum ether. The solution was filtered and concentrated in vacuo to give 0.7 g N-3-[4-(2-chlorophenyl)piperazin-1-yl]propyl-N'-(3,4-ethylenedioxyphenyl)carbodiimide as an oil.
