2-tert-Butyl-6-methylaniline → N-(2-tert-butyl-6-methylphenyl)-N'-methyl-N'-(2-phenylcyclohexyl)urea

Participants

Reaction Steps

To a solution of 0.82 g of 2-tert-butyl-6-methylaniline in pyridine is added a solution of 1.2 g of N-methyl-N-(2-phenylcyclohexyl)carbamoylchloride in dichloromethane dropwise. The mixture is stirred at room temperature until starting compounds disappear on TLC. The mixture is concentrated and the residue is dissolved in ethyl ether. The solution is washed with diluted hydrochloric acid, aqueous sodium hydrogencarbonate solution and brine. The organic layer is dried over sodium sulfate and filtered off. The filtrate is distilled away and the resuling residue is crystallized to give N-(2-tert-butyl-6-methylphenyl)-N'-methyl-N'-(2-phenylcyclohexyl)urea.
