Reaction Steps
Dimethylamine (50% solution in water, 20 mL) was added to a stirred solution of 2-chloro-4-methyl-5-nitropyridine (15.0 g, 86.9 mmol) in tetrahydrofuran (150 mL), and the mixture was stirred at 0° C. for 2 hr. The mixture was concentrated in vacuo, diluted with saturated aqueous sodium hydrogen carbonate and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the title compound as a yellow solid (15.7 g, 86.6 mmol, 99%).
