Reaction Steps

To a solution of 4-{2-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-ethyl}-morpholine (can be prepared as described in US2002026052) (101 mg, 0.31 mmol) and 5-bromo-3-(1-isopropyl-1H-[1,2,3]triazol-4-yl)-pyridin-2-ylamine (90 mg, 0.31 mmol) in 1,4-dioxane (7.0 mL)/water (3.0 mL) was added Cs2CO3 (251 mg, 0.70 mmol) at RT. N2 was purged through the reaction mixture for 10 min. Pd(PPh3)4 (18 mg, 0.015 mmol) was added and through the reaction mixture N2 was purged for 10 min and stirred at 100° C. for 16 h. The reaction mixture was cooled to RT, diluted with EtOAc (50 mL) and washed with water (50 mL). The organic layer was washed with brine solution (50 mL), dried over anhydrous Na2SO4 and solvent was evaporated under reduced pressure to afford crude compound (GVK-B1319-120A1). Crude compound was purified by column using 100-200 mesh silica gel and eluted with 2-3% MeOH in DCM to afford 65 mg of a brown semisolid. Further purification of Prep-HPLC furnished 14 mg of the title compound as an off-white solid.
