Reaction Steps

A solution of 5.30 g of 1-benzyl-1-(n-butyl)-3-(4-carboethoxyphenyl)urea in 100 ml of ethanol is treated with 25 ml of 1N aqueous sodium hydroxide, stirred under reflux for 16 hours, allowed to cool, acidified with 1N hydrochloric acid, and filtered. The solid is recrystallized from ethanol to yield 1-benzyl-1-(n-butyl)-3-(4-carboxyphenyl)urea as a white solid.
