Procedure

First, 0.8 g of sodium hydride was added to a mixture of 3.17 g of 2-chloro-3-nitropyridine, 2.19 g of methyl lactate, and 20 ml of 1,4-dioxane at 10° C., and the mixture was stirred at room temperature for 1.5 hours. The reaction mixture was poured into ice water, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography to give 3.3 g of 2-{1-(methoxycarbonyl)ethoxy}-3-nitropyridine.
