실험 절차

To a solution of 1.8 g of 2-chloro-3-nitro-5-(trifluoromethyl)pyridine in 8 mL of tetrahydrofuran, 2.0 mL of triethyl 1,1,2-ethanetricarboxylate and 0.63 g of 60% sodium hydroxide were added under cooling with ice, and the mixture was stirred at room temperature for 2 hours. Thereto were added water and ethyl acetate, the organic layer was separated, and washed with a saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to obtain 3.5 g of triethyl 1-(3-nitro-5-(trifluoromethyl)pyridin-2-yl)ethane-1,1,2-tricarboxylate as a brown oily substance.
