Reaction Steps
A 100 mL single necked flask fitted with a magnetic stirrer and a reflux condenser was charged with a 10.0 g (32 mmol) of 3-pentadecylcyclohexanone, 8.4 g (65 mmol) aniline hydrochloride and 12.05 g (130 mmol) of aniline. The resulting mixture was refluxed at 140° C. for 10 hours under positive pressure of nitrogen. The reaction mixture was cooled to room temperature, diluted with dichloromethane, and washed with aqueous sodium hydroxide solution and water and dried over sodium sulfate. Solvent was distilled off and excess aniline removed under vacuum. The desired 1,1-bis(4-aminophenyl)-3-pentadecylcyclohexan was obtained in a yield of 5.4 g (35% of theoretical). M.p. 107° C.
