Reaction Steps
To a solution of 1.0 g of 2-amino-4-methyl-5-nitropyridine in 10 mL of diiodomethane was added 1.8 mL of isopentyl sulfite at room temperature, stirred at this temperature for 30 minutes, and after raising the temperature to 80° C., the solution was stirred for 2 hours. The diiodomethane was evaporated, and the crude product was purified and separated by silica gel column chromatography (ethyl acetate:n-hexane=1:20), to afford 897 mg of the title compound as colorless crystals.
