実験手順
Suspend 4-phenyl-1-(phenylmethyl)-2-piperazinecarboxamide (14.5 g, 49 mmol)in ethylene glycol (400 mL) and add potassium hydroxide (27.5 g, 490 mmol).Heat this mixture to 150° C. for 18 h. After this time, remove the solvent in vacuo. Add 6M hydrochloric acid (81.5 mL, 0.49 mol) and water (300 mL) and filter the resultant solid to obtain the title compound.
