1-Phenylethylamine is the organic compound with the formula C6H5CH(NH2)CH3. Classified as a monoamine, this colorless liquid is often used in chiral resolutions. Like benzylamine, it is highly basic and forms stable ammonium salts and imines.

This compound may be prepared by the reductive amination of acetophenone. One major route for this chemical uses the Mignonac reaction, a one-pot protocol using hydrogen gas as the reducing agent:[1]

Reductive amination acetophenone ammonia

The Leuckart reaction, using ammonium formate, is another method for this transformation.[2]

L-malic acid is used to resolve 1-Phenylethylamine, a versatile resolving agent in its own right. The dextrorotatory enantiomer crystallizes with the malate, leaving the levorotatory form in solution.[3]
