실험 절차

To a solution of 2-chloro-1,3-dinitrobenzene (2.94 g, 14.54 mmol) in methanol (30.0 mL) were added 3-amino-2,2-difluoropropanoic acid (2.0 g, 15.99 mmol), sodium hydrogen carbonate (2.69 g, 31.98 mmol) and water (15 mL). The reaction mixture was stirred at 80° C. for 1 day. The starting material wasn't consumed completely. To the mixture was added sodium hydrogen carbonate (5.88 g, 63.96 mmol) and the mixture was stirred at 80° C. for 0.5 day. After cooling, the solvent was removed. The residue was neutralized with 1N hydrochloric acid (100 mL) and extracted with ethyl acetate (×3). The combined organic layer was washed with brine (×1), dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the title compound as a yellow solid (3.52 g, 12.09 mmol, 83%).
