white crystalline powder

N,N''-Dicyclohexylurea,is a substituted Urea (U822500) compound, which has shown to be a potent inhibitor of juvenile hormone epoxide hydrolase (JHEH) of the tobacco hornworm M. sexta. Lomustine USP Related Compound C.

?? ??

An excess of dry ice (200 g) was added gradually to a solution of dicyclohexylcarbodiimide (2.06 g, 0.01 mol), cyclohexylamine (1.98 g, 0.02 mol), and triethylamine (2.2 g, 0.02 mol) in THF at 75 ℃ over a period of 8 h. After stirring for 8 h, the reaction mixture was concentrated under reduced pressure and the resultant precipitate was collected. Fractional recrystallization of the precipitate from acetone/methanol gave N,N'-dicyclohexylurea; yield 2.2 g (98% based on dicyclohexylcarbodiimide and cyclohexylamine).
