Procedure
Cyclopropanemethylamine hydrochloride (Aldrich, 1.00 g, 9.30 mmol) and triethylamine (0.95 g, 9.39 mmol) were dissolved in chloroform (10 mL). 1,1'-Carbonyldiimidazole (Aldrich, 0.754 g, 4.65 mmol) was added and the resulting solution maintained at ~55° C. for 22 h. The chloroform solution was extracted with 1N hydrochloric acid (2×50 mL) and then with water (50 mL) and dried. Evaporation of the chloroform gave crude product (650 mg) which was recrystallized from toluene to give 1,3-bis(cyclopropylmethyl)urea as white crystals (462 mg, 59%), m.p. 127°-130° C.; 1H-NMR (DMSO-d6) consistent with structure.
