Reaction Steps

A solution of 15 g (95 mmol) of ethyl trimethyl-pyruvate and 50 g (413 mmol) of (S)-1-phenylethylamine in 50 ml of xylene was boiled under reflux on a water separator for 18 hours. Subsequently, the solvent was distilled off and excess amine was removed at 120° C. in a vacuum. After crystallization of the distillation residue from 125 ml of hexane there were obtained 14.3 g (45%) of (S)-3,3-dimethyl-N-[(S)-1-phenylethyl]-2-(1-phenylethylimino)-butyramide of melting point 96°-97° C. [α]=-58.9 (c=1.0, CHCl3).
