Conditions

Temperature: 40 °C

Procedure

4-{(S)-4-tert-butoxycarbonyl-2-[(6-chloro-2-phenyl-pyrimidine-4-carbonyl)-amino]-butyryl}-piperazine-1-carboxylic acid ethyl ester (53 mg) and propylamine (31 μl) were dissolved in THF (0.5 ml). The mixture was stirred at 40° C. until reaction completion. Water was added and it was extracted with EA. The org. layers were dried (Na2SO4) and evaporated off to give 60 mg of the desired pure compound.
