실험 절차

A stirred solution of 6.13 g of 3-[2-(4-aminopiperazin-1-yl)ethyl]indole and 3.53 g of phenylisocyanate in 100 ml. of dry benzene is refluxed for 6 hours and then allowed to stand at ambient temperature overnight. Ether is added slowly to promote crystallization. The solid product is filtered, washed with ether and dried. The solid is recrystallized twice from a dimethylformamide water mixture to give crystals m.p. 168°-171° C. of 1-[1-(indol-3-ylethyl)piperazin-4-yl]-3-phenylurea.
