Reaction Steps
To a mixture of 5-bromo-3,4-dimethylpyridin-2-amine (0.6 g, 3.0 mmol) and H2SO4 (98%, 1.62 mL) and H2O (18 mL) is added a solution of NaNO2 (243.6 mg, 4.2 mmol) in H2O (1.6 mL) drop-wise at 0° C. Then, it was stirred at 31° C. for 30 minutes and filtered. The resulting solid is washed with water to provide the title compound (375.0 mg, 62%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ 7.48 (s, 1H), 2.32 (s, 3H), 2.19 (s, 3H). LCMS (M+H)+ 202.
