Procedure

N-(3-methoxycarbonyl-2-methylpropanoyl)-L-alanine benzyl ester (50 g.) is dissolved in 95% ethanol, 10% palladium on charcoal (5 g.) is added and the mixture is hydrogenated at normal pressure for 16 hours. The catalyst is filtered off and the filtrate is concentrated to dryness in vacuo to yield N-(3-methoxycarbonyl-2-methylpropanoyl)-L-alanine.

Workup

  1. filtrationThe catalyst is filtered off
  2. concentrationthe filtrate is concentrated to dryness in vacuo
