Reaction Steps

To a solution of 5-bromo-3-(5-cyclopropyl-[1,3,4]oxadiazol-2-yl)-pyridin-2-ylamine (400 mg; 1.42 mmol) in dioxane (10 mL) and water (6 mL) were added K2CO3 (587 mg; 4.26 mmol), (3-(morpholinomethyl)phenyl)boronic acid (348 mg; 1.56 mmol) in a sealed tube. The reaction mixture was degassed with argon for 30 min, then added Pd(PPh3)4 (82.0 mg; 0.07 mmol) to the reaction mixture. The reaction mixture was stirred for 18 h at 100° C. The reaction mixture was diluted with water (50 mL) extracted with ethyl acetate (2×50 mL) and organic layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. Crude compound was purified by column chromatography using 100-200 mesh silica gel and eluted with 100% ethyl acetate, which is further purified by washing with 30% chloroform in hexane to afford 90 mg (Yield: 16.7%) of the title compound, as a yellow colour solid.
