PROCEDURE

实验过程

To a solution of 1.50 g 5-[2-((S)-2-(Cyclopropylmethyl-carbamoyl)-pyrrolidin-1-yl)-2-oxo-ethoxy]-1-phenyl-1H-pyrazole-3-carboxylic acid in 22 ml DMF were added 0.60 ml DIPEA, 1.38 g HATU and 923 mg H-Glu(OtBu)-OMe hydrochloride. After stirring for 24 h the solution was concentrated, taken up with dichloromethane and subsequently extracted with aqueous LiCl (4%), 0.1 M HCl and saturated NaHCO3. The crude product obtained after evaporation of the solvent was purified by chromatography on silica using DCM/MeOH 97:3 as eluent. Yield: 2.0 g.
