Reaction Steps

Triethylamine (53 μl) and 2-methoxyethylamine (23 mg) were added to a tetrahydrofuran (2 ml) solution containing 3-bromo-2-chloro-5-nitropyridine (60 mg), followed by stirring at room temperature for 1 hour. Water was added to the reaction solution, followed by extraction with ethyl acetate. The resultant was washed with saturated saline and dried over anhydrous sodium sulfate. Subsequently, the solvent was distilled away under reduced pressure, the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=6:1 to 3:1), and a light yellow solid of 3-bromo-N-(2-methoxyethyl)-5-nitropyridin-2-amine (93.5 mg) was thus obtained.
