To a solution of 1-isopropyl-4-(5-methyl-pyridin-2-yl)-1H-indazole-6-carboxylic acid (0.24 g, 0.814 mmol) in acetonitril was added C-(5-methyl-pyrazin-2-yl)-methylamine (0.12 g, 0.976 mmol), EDCI (0.23 g, 1.22 mmol), HOBt (0.16 g, 1.22 mmol), and NMM (0.45 mL, 4.07 mmol). The reaction mixture was stirred at room temperature overnight, then partitioned between water and ethyl acetate. The organic layer was separated, dried over MgSO4, filtered and concentrated under reduced pressure. Purification of the residue by column chromatography gave 0.144 g (44%) of 1-isopropyl-4-(5-methyl-pyridin-2-yl)-1H-indazole-6-carboxylic acid (5-methyl-pyrazin-2-ylmethyl)-amide MS (M+H)=401.
