実験手順
Carboxamide 229 (0.0108 g, 0.0153 mmol) was dissolved in 1 mL of dichloromethane. To this was added 0.4 mL of triethylsilane and 0.2 mL of trifluoroacetic acid. Stirred at room temperature and after ten minutes complete by TLC. Concentrated off volatiles, azeotroped with toluene to give crude. Then dissolved in 0.6 mL dichloromethane, 0.6 ml trifluoroacetic acid. Stirred at room temperature for one hour. 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-5-(piperazine-1-carbonyl)-6,7-dihydro-pyrrolo[3,4-g]quinolin-8-one 230 (0.039 g, 0.0682 mmol, 100%.) 1H NMR (CD3SOCD3) δ 98.97 (s, 2H), 8.32 (d, 1H), 7.74 (s, 1H), 7.36 (dd, 2H), 7.19 (dd, 2H), 4.86 (d, 1H), 4.58 (d, 1H), 4.42 (d, 1H), 4.34 (d, 1H), 3.9-2.90 (m, 8H.) 19F NMR: −74.202 MS: 421 (M+1), 419 (M−1)
