실험 절차

A solution of 5.61 g. of 1,1-dibenzyl-3-(4-carboethoxyphenyl)urea in 100 ml of ethanol is treated with 25 ml of 1 N aqueous sodium hydroxide solution, stirred under reflux for 16 hours, allowed to cool, acidified with 1 N hydrochloric acid, and filtered. The solid is recrystallized from ethanol to yield 1,1-dibenzyl-3-(4-carboxyphenyl)urea as a white solid, mp 210°-214°.
