Reaction Steps

4-{(S)-2-[(6-cyclopentyloxy-2-phenyl-pyrimidine-4-carbonyl)-amino]-4-hydroxy-butyryl}-piperazine-1-carboxylic acid ethyl ester (16.8 mg) was dissolved in THF (1 ml) under argon and cooled to 0° C. A solution of potassium bis-(trimethylsilyl)-amide (0.5 M in toluene, 8 μl) and, 5 min later, ethylbromoacetate (5 μl) were added. The mixture was stirred at 0° C. for 1 h and evaporated off. The residue was taken up in water and extracted twice with EA. The org. layers were washed with water, a NaCl solution, dried (Na2SO4) and evaporated off to give 19 mg of the desired compound.
