実験手順
5-Methoxyisoindoline (8.34 g, 55.97 mmol) in 48% aqueous hydrobromic acid (100 ml) was stirred and held at reflux for 16 hours. Upon cooling to room temperature the solvent was removed in vacuo to afford 5-hydroxyisoindoline hydrobromide (11.32 g, 93%) as a tan solid. 1H NMR (DMSO-d6) 9.63 (1H, br s), 9.32 (2H, br s), 7.18 (1H, d), 6.79 (1H, d), 6.76 (1H, dd), 4.42 (2H, t), 4.38 (2H, t). MS: [M+H]+ 136.
