Absolute configuration of N-(R)-3-methyl-2-butyl-(S)-2-(6-methoxy-2-naphthyl)propionamide
Abstract
The title compound, C19H25NO2, was made in order to confirm the absolute configuration of (R)-3-methyl-2-butylamine obtained from commercially available (R/S)-3-methyl-2-butylamine (racemate) after fractional crystallization of its ammonium salt with the optically pure carboxylic acid derivative, (S)-naproxene.
