Cyclopropylamine → N-[(5-Chloro-2-isopropylphenyl)methylene]cyclopropanamine

Participants

Reaction Steps

Cyclopropylamine (39.2 g, 0.69 mol) was added to a solution of 5-chloro-2-isopropylbenzaldehyde (II) (120 g, 0.65 mol, 99.6 GC-% by area) in methanol (1200 ml) and the mixture was stirred at room temperature for 2 hours. The solvent was subsequently removed under reduced pressure and N-[(5-chloro-2-isopropylphenyl)-methylene]cyclopropanamine (144 g, 99.2 GC-% by area, 98.5% of theory) was obtained as a light-yellow oil.
