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 2-methylaminopyridine (0.0079 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 methyl-pyridin-2-yl-amide 318 (0.0017 g, 0.003 mmol, 8%.) 1H NMR (CDCl3) δ 9.02 (dd, 1H), 8.50 (d, 1H), 8.18 (d, 1H), 7.65 (dd, 1H), 7.38 (m, 5H), 7.08 (dd, 2H), 4.94 (dd, J=15 Hz, 11Hz, 2H), 4.49 (d, J=17 Hz, 1H), 4.19 (d, J=17 Hz, 1H), 3.61 (s, 3H.) MS: 443 (M+1).
