Sodium Carbonate → N-methoxy-N-methyl-3-((3-nitropyridin-2-yl)amino)cyclobutanecarboxamide

Participants

Reaction Steps

To a solution of 3-amino-N-methoxy-N-methylcyclobutanecarboxamide (0.606 g, 3.84 mmol) in dry dimethylformamide (15 mL) was added sodium carbonate (1.22 g, 11.5 mmol) and 2-chloro-3-nitropyridine (608 mg, 3.84 mmol). The reaction mixture was stirred and heated at reflux for 14 hours. The reaction mixture was diluted with water (25 mL) and extracted with ethyl acetate (2×30 mL). The combined organic extracts were washed with water (30 mL), brine (30 mL) and dried over sodium sulfate. The filtrate was evaporated in vacuo and the residue was purified by column chromatography on silica gel (20% to 50% ethyl acetate in petroleum ether) to give N-methoxy-N-methyl-3-((3-nitropyridin-2-yl)amino)cyclobutanecarboxamide (0.86 g, 3.07 mmol, 80% yield) as yellow solid.
