Reaction Steps

To a solution of 5-bromo-3-(1-isopropyl-1H-[1,2,3]triazol-4-yl)-pyrazin-2-ylamine (750 mg, 2.65 mmol) and N-methylindole-5-boronic acid (556 mg, 3.18 mmol) in 1,4-dioxane (15.0 mL)/water (5.0 mL) was added Cs2CO3 (1.29 g, 3.97 mmol) at room temperature. The reaction mixture was purged with argon for 30 min. Then Pd(PPh3)4 (153 mg, 0.13 mmol) was added and allowed to stir at 100° C. for 16 h. The reaction mixture was cooled to RT, diluted with EtOAc (20 mL) and washed with water (20 mL). The organic layer was washed with brine solution (20 mL), dried over anhydrous Na2SO4 and solvent was evaporated under reduced pressure to afford crude product. The crude compound was purified by column using 100-200 mesh silica gel. The column was eluted with 70-80% EtOAc in Hexane to afford the title compound as a yellow solid.
