Reaction Steps

4.2 g of Compound [II] was dissolved in 50 ml of methylene chloride, and 4.1 g of N,N-diethylcarbamoyl chloride was added to the solution. The mixture was heated under refluxing for 5 hours and cooled, followed by washing with water. The organic layer was collected, and the solvent was distilled off. The residue was subjected to crystallization by the addition of hexane. The crystals obtained were collected by filtration and dried to obtain 3.2 g of N,N-diethyl N'-(5-t-butyl-3-pyrazolyl)urea.
