Procedure

3-(8-Fluoro-1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)-2-oxo-5-oxazolidinecarboxylic acid methyl ester (EXAMPLE 82, Step 5, 0.300 g, 9.31 mmol) is dissolved in 2M methylamine 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 (0.145 g, 48%), mp 264-5° C.; 1H NMR (300 MHz, CDCl3) δ 2.47-2.52 (m, 2H), 2.64 (d, 3H), 2.84-2.89 (m, 2H), 3.27 (d, 3H), 4.00 (dd, 1H), 4.24 (t, 1H), 5.06 (dd, 1H), 7.26 (s, 1H), 7.46 (dd, 1H), 8.39 (d, 1H); MS for C15H16FN3O4 m/z 322 (M+H)+.
