Reaction Steps

To a solution of 100 mg ({5-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carbonyl}-amino)-acetic acid in 2 ml DMF were added 0.15 ml DIPEA, 81 mg HATU and 0.03 mg 1-cyclobutoxycarbonylpiperazine. After stirring for 1 h it was diluted with dichloromethane and extracted with aqueous LiCl (4% w/w), aqueous NaHCO3 and 0.1 M HCl. The crude product obtained after evaporation of the solvent was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA) to give the title compound.
