実験手順

A mixture of cyclohexanemethylamine (Aldrich, 68.66 g) and 5 N sodium hydroxide (Fisher, 200 ml) was stirred vigorously with cooling (−10° C.) while a solution of phosgene (30.0 g) in toluene (600 ml) was added rapidly. After stirring for 20 minutes, the resulting mixture was filtered and the precipitated solid was washed with water and dried (0.5 Torr) to give 1,3-bis(cyclohexylmethyl)urea as white powder (72.72 g, 95%), m.p. 150-152° C.; 1H-NMR (DMSO-d6) δ: 5.74 (br t, J=5.8 Hz, 2, 2 NH), 2.81 (t, J=6.3 Hz, 4, 2 NCH2), 1.62, 1.25, and 0.85 (all m, 22, 2 cyclohexyl).
