실험 절차

Carboxamide 231 (0.225 g, 0.355 mmol) was dissolved in 1 mL of dichloromethane. To this was added 0.5 mL of triethylsilane and 0.25 mL of trifluoroacetic acid. Stirred at room temperature and after ten minutes complete by TLC. Concentrated off volatiles, azeotroped with toluene to give crude. Triturated twice with 1:1 diethyl ether/hexanes to give 7-(4-fluoro-benzyl)-9-hydroxy-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinoline-5-carboxylic acid (pyridin-2-ylmethyl)-amide 232 (0.11 g, 0.20 mmol, 56%.) 1H NMR (CD3SOCD3) δ 9.18 (s, 1H), 8.96 (d, 1H), 8.65 (dd, 2H), 8.09 (dd, 1H), 7.76 (dd, 1H), 7.64 (dd, 1H), 7.36 (dd, 2H), 7.22 (dd, 2H), 4.70 (s, 4H), 4.54 (s, 2H). 19F NMR: −75.37 MS: 443 (M+1), 441 (M−1)
