Procedure

Cs2CO3 (682 mg, 2.10 mmol) was added to a solution of 5-bromo-3-(1-isopropyl-1H-[1,2,3]triazol-4-yl)-pyridin-2-ylamine (200 mg, 0.70 mmol) and (3-chloro-4-(morpholine-4-carbonyl)phenyl)boronic acid (229 mg, 0.85 mmol) in dioxane: water (7 mL: 3 mL) degassed the reaction mixture for 10 min with nitrogen. Then added Pd(PPh3)4 (40 mg, 0.035 mmol), degassed the reaction mixture for additional 10 min with nitrogen, the reaction mixture was heated to 120° C. in microwave for 1 h. The reaction mixture was diluted with water (50 mL) and extracted with ethyl acetate (3×30 mL). Combined organic layers was dried over Na2SO4 and concentrated under reduced pressure. Crude product was purified by silica (100-200 mesh) column eluted with 70-80% ethyl acetate in pet-ether to afford 68 mg (Yield: 22.5%) of the title compound as a pale yellow solid. Product was converted to its HCl salt by using HCl in ether (2M) to afford 60 mg of the HCl salt of the title compound as a pale yellow solid.
