Water → (R)-[1-(4-chlorophenyl)-ethyl]-[1-phenyl-ethylidene]-amine

Participants

Reaction Steps

0.3 g of zinc chloride is added to a solution of 20 g (0.128 mol) of (R)-1-(4-chlorophenyl)-ethylamine (97% ee) and 15.6 g (0.13 mol) of acetophenone in 70 ml of toluene at room temperature with stirring, and the mixture is then refluxed for 74 hours at the water separator. The reaction mixture is then filtered. The filtrate is evaporated under reduced pressure to give 15.56 g (47% of theory) of (R)-[1-(4-chlorophenyl)-ethyl]-[1-phenyl-ethylidene]-amine.
