실험 절차

To a solution of 100 mg 5-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carboxylic acid (2-oxo-2-piperazin-1-yl-ethyl)-amide in 5 ml dichloromethane were added at 0° C. 56 l DIPEA and 25 l butyl isocyanate. After stirring for 12 h it was concentrated and the residue obtained was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA) to give the title compound. Yield: 55 mg MS (ES+): m/e=637.
