実験手順

To a suspension of imidazo[1,2-a]pyridine-3-carboxylic acid (45.1 mg, 0.278 mmol) in NMP (5 mL) was added 2,4,6-trichlorobenzoyl chloride (43.5 μL, 0.278 mmol) and triethylamine (38.8 μL, 0.278 mmol). The reaction mixture was stirred for 30 minutes. 1-((1,5-Dimethyl-1H-pyrazol-3-yl)methyl)-3-ethyl-1H-indazol-4-amine (50 mg, 0.186 mmol) was added to the reaction mixture, which was heated to 87° C. for 3 hours. The mixture was cooled to ambient temperature, and diluted with 10% NaOH aqueous solution (5 mL) and EtOAc (20 mL). The organic phase was washed with water and brine, then concentrated under reduced pressure. The residue was triturated with Et2O to give final product (35 mg). MS (ES+APCI) m/z=414 (M+H).
