Participants

Reaction Steps

A mixture of 2-chloro-5-methyl-4-nitropyridine 1-oxide (1.1 g, 5.8 mmol), 1-(2,4-dimethoxyphenyl)methanamine (1.1 mL, 7.0 mmol), DIEA (2.0 mL, 11.6 mmol), and 1-butanol (9 mL) was subjected to microwave irradiation at 120° C. for 8 h. The reaction mixture was allowed to cool to rt and was filtered. The resulting solid was washed with water (20 mL) and dried to give N-(2,4-dimethoxybenzyl)-5-methyl-4-nitropyridin-2-amine 1-oxide (1.2 g, 67%), which was used in the next step without further purification.
