Cyclohexanone → butyl-cyclohexylideneamine

Participants

Reaction Steps

1-Butylamine (9.88 mL, 0.1 mol) and toluene (15 mL) was added to cyclohexanone (10.36 mL, 0.1 mol) and the reaction mixture was heated under reflux for 24 h under dehydration condition by using Dienstark reflux condenser packing molecular sieves 4A. After the reaction mixture was cooled to room temperature, evaporated under reduced pressure. The residue was distilled under reduced pressure (2 mmHg) at 64° C. to give butyl-cyclohexylideneamine (1-015-01) (12.8 g, 84%) as a colorless oil.
