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) (1.5 g g, 4.2 mmol), Phenyl chloroformate (Compound 55a) (0.76 mL, 6.3 mmole) and THF (10 mL) was added Diisopropylethylamine (DIPEA) (1.4 mL, 8.4 mmole) at room temperature with stirring. The reaction was stirred at room temperature over night. The reaction was quenched with saturated sodium bicarbonate and extracted with ethyl acetate. The solvent was dried over sodium sulfate and removed via rotovap to give a crude material (Compound 433). MS m/z 446.1 (M+H)+.
