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 (40 mg), glycine ethyl ester hydrochloride (23.8 mg) and NEt3 (20 l) were dissolved in THF (0.5 ml). The mixture was stirred at 40° C. until reaction completion. Water was added to the reaction mixture which was extracted with EA. The org. layers were dried (Na2SO4) and evaporated off to give 41 mg of the desired pure compound.
