실험 절차

3-(8-Fluoro-1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)-2-oxo-5-oxazolidinecarboxylic acid methyl ester (Step 5, 0.300 g, 9.31 mmol) is dissolved in 2M ammonia in methanol solution (8 ml) and stirred overnight at room temperature. The resulting precipitate is filtered, washed with methanol, and dried under vacuum to give the title compound as a white solid (0.185 g, 65%), mp 260-2° C.; 1H NMR (300 MHz, CDCl3) δ 2.48-2.52 (m, 2H), 2.85-2.89 (m, 2H), 3.28 (d, 3H), 4.00 (dd, 1H), 4.24 (t, 1H), 5.03 (dd, 1H), 7.27 (s, 1H), 7.46 (dd, 1H), 7.62 (br s, 1H), 7.87 (br s, 1H); MS for C14H14FN3O4 m/z 308 (M+H)+.
