Procedure

9-Benzhydryloxy-7-(4-fluoro-benzyl)-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinoline-5-carboxylic acid 213 (0.02 g, 0.0386 mmol) was dissolved in 0.3 mL of dimethylformamide. To this was added dimethylamine (2M in THF) (0.0386 mL, 0.0772 mmol), diisopropylethylamine (0.027 mL, 0.1544 mmol), O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.03 g, 0.0772 mmol) and stirred at room temperature. After 15 hours, starting material was consumed. Purified by reverse phase HPLC (0.1% TFA, H2O/ACN) to give 7-(4-fluoro-benzyl)-9-hydroxy-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinoline-5-carboxylic acid dimethylamide 321 (0.014 g, 0.037 mmol, 97%.) 1H NMR (CDCl3) o9.07 (dd, 1H), 8.18 (d, 1H), 7.65 (dd, 3H), 7.03(dd, 2H), 4.79 (dd, 2H), 4.53 (d, J=17 Hz, 1H), 4.25 (d, J=17 Hz, 1H), 3.24 (s, 3H), 3.21 (s, 3H.) MS: 380 (M+1).
