Reaction Steps
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 diethylamine (0.0056 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 diethylamide 322 (0.0134 g, 0.033 mmol, 86%.) 1H NMR (CDCl3) δ 9.07 (dd, 1H), 8.18 (d, 1H), 7.65 (m, 3H), 7.07(dd, 2H), 4.72 (dd, 2H), 4.56 (d, J=17 Hz, 1H), 4.23 (d, J=17 Hz, 1H), 3.66 (q, 2H), 3.11 (q, 2H), 1.35 (t, 3H), 0.965 (t, 3H.) MS: 408 (M+1).
