Reaction Steps
Into a 50-mL sealed tube, was placed a solution of 6-bromo-5-methylpicolinimidamide (compound 350.3, 800 mg, 3.74 mmol, 1.00 equiv) and CuSO4 (80 mg) in NH3.H2O (40 mL). The resulting mixture was stirred overnight at 80° C. behind a blast shield. After cooling to ambient temperature, the mixture was then extracted with 2×50 mL of ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated under reduced pressure to yield 750 mg (crude) of the title compound as a brown solid.
