Aniline → Benzenamine, N-(2-methylcyclohexyl)-

Participants

Reaction Steps

In a 100-mL flask, the following mixture is heated at reflux for 30 h: 9.3 g aniline, 11.2 g 2-methylcyclohexanone and 12 g benzotriazole. Then, 200 mL of methanol and 5 g of NaBH4 in portions are added to the mixture, which is then heated at reflux for 30 min. The solution is allowed to cool, and 100 mL of water are added to the mixture, which is extracted with 2×100 mL diisopropyl ether. The organic phase is recovered, dried over magnesium sulfate and reduced to dryness. In this manner, 7 g of the desired amine are produced.
