Cyclohexylamine → HCID 525618, compound

Participants

Reaction Steps

To the solution of (α-chlorobenzylidene)dimethylammonium chloride in methylenechloride described in Example 1, there was added dropwise, a solution of 49.6 g (0.5 mole) of cyclohexylamine in 100 ml of methylenechloride. The temperature of the ensuing exothermal reaction rose from 24.5° to 42.5° C. thus keeping the solvent in reflux. After the reaction subsided, the reaction mixture, consisting of a slurry of white solids in a pale yellow solution, was heated to reflux with stirring. After standing overnight, the slurry was filtered, and the solution was stripped of the solvent and the oily residue distilled. The novel amidine (also called N'-cyclohexyl-N,N-dimethylbenzenecarboximidamide) was obtained as a colorless oil, boiling between 78° and 79° C. at 0.04 mm of mercury pressure and having a refractive index of nD 21.6, 1.5400, in 56.0 g corresponding to a 49% yield. Proton nmr infrared and elemental analysis confirmed its proposed structure.
