A mixture of 3-(1-(6-chloropyridazin-3-yl)-1H-pyrazol-4-yl)-6-fluoro-1-(phenylsulfonyl)-1H-indole (Intermediate 44; 136 mg; 0.30 mmol) and 2,4-dimethoxybenzylamine (100 mg; 0.60 mmol) in NMP (2 mL) was stirred at 200° C. for 2 hours under a microwave reactor. The reaction mixture was diluted with EtOAc (30 mL), washed water (10 mL), brine (10 mL), dried over anhydrous Na2SO4, filtered, concentrated, and purified by a silica gel column chromatography (petroleum ether/EtOAc=4/1 to 2/1) to afford 120 mg (68%) of the title compound as a white solid.
