Procedure

To a solution of 283b (11 mg) dissolved in dichloromethane (1 mL) was added trifluoroacetic acid (100 μl) and triethylsilane (200 μl). The reaction mixture was stirred at room temperature for ½ hours under an inert atmosphere then concentrated in vacuo. The residue was triturated with diethyl ether/hexane (1/1) to afford 7-(4-fluoro-benzyl)-9-hydroxy-6,7-dihydro-pyrrolo[3,4-g]quinolin-8-one 285, TFA salt, (3.9 mg) as a yellow solid: 1H NMR (CDCl3) δ 9.1 (d, 1H), 8.3 (d, 1H), 7.6 (m, 1H), 7.35 (s, 1H), 7.33 (m, 2H), 7.0 (t, 2H), 4.8 (s, 2H), 4.4(s, 2H); MS: 309 (M+1).
