実験手順

50 mg of 4-((S)-4-Carboxy-2-{[5-(1-ethoxycarbonyl-cyclobutoxy)-1-phenyl-1H-pyrazole-3-carbonyl]-amino}-butyryl)-piperazine-1-carboxylic acid ethyl ester were dissolved in 1 ml of a 8 M solution of ammonia in methanol. After 16 h at RT the solvents were evaporated under reduced pressure and the residue was purified by preparative HPLC (C18 reverse phase column, elution with a water/MeCN gradient with 0.1% TFA). The fractions containing the product were evaporated and lyophilized to yield a white solid.
