실험 절차

To a mixture of (6,7-Dimethoxy-1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-(3-fluoro-phenyl)-amine (Compound 14) (0.50 g, 1.5 mmol), 3-Chlorocarbonyl-propionic acid methyl ester (Compound 26a) (0.277 g, 1.8 mmole) and DMF (1.5 mL) was added Duisopropylethylamine (DIEA) (0.52 mL, 3.0 mmole) at room temperature with stirring. The reaction was stirred at room temperature over night. The reaction was quenched with water and extracted with EtOAc. The solvent was removed via rotovap and the crude material was prepped on the reverse phase HPLC. Lyophilization gave the title compound as-a white powder. MS m/z 439.9 (M+H)+;
