実験手順

1-[2-(3,3-Dicyclohexyl-ureido)-thiazol-5-ylmethyl]-pyrrolidine-2(R)-carboxylic acid benzyl ester (50 mg, 0.095 mmol) was combined with palladium on carbon (25 mg) in MeOH. Vacuum was applied to degas the mixture. The reaction was subjected to hydrogen and vigorous stirring until no ester could be detected (36 h). After filtering and concentration, 35 mg (84%) pure acid was obtained by trituration.
