Procedure
To a solution of (S)—((R)-1-(4-(3-fluoro-4-(7-methoxyquinolin-4-yloxy)phenyl carbamoyl)-5-methyl-3-oxo-2-phenyl-2,3-dihydropyrazol-1-yl)propan-2-yl)2-amino-propanoate (61.3 mg, 0.1 mmol) in EtOAc (15 mL)/MeOH (10 mL) was added maleic acid (23.2 mg, 0.2 mmol, Shantou Xilong chemical factory). After stirring for 40 min, the mixture was concentrated in vacuo, and the resulted oil was washed with a mixture of MeOH (2 mL)/EtOAc (10 mL) followed by EtOAc (5 mL×3) to give the title compound as yellow oil (62.6 mg, 85.6%).
Workup
