Reaction Steps
To a solution of 250 mg 5-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carboxylic acid in 4 ml DMF were added 124 mg HOAt, 174 mg EDC, 0.37 ml DIPEA and 136 mg leucine tert-butyl ester hydrochloride. After stirring for 12 h it was concentrated and the residue dissolved in dichloromethane. It was extracted with aqueous LiCl (4% w/w), aqueous NaHCO3 and 0.1 M HCl. The organic layer was dried over MgSO4 and concentrated to furnish the crude coupling product as colorless oil.
