Procedure

A solution of compound 5-C (5.35 g, 16.7 mmol) in MeOH (75 mL), was heated at reflux for 6 hours. The solution was cooled to rt, and the solvent was evaporated in vacuo. The residue was dissolved in water and made basic with aqueous NaHCO3, to give a solid precipitate. The solid was collected by filtration, dissolved into EtOAc, and dried over sodium sulfate. The solvent was evaporated in vacuo to give compound 5-D as a pale pink solid (3.4 g, 92%). 1H-NMR (CDCl3): δ 7.82-7.86 (m, 1H), 7.64-7-68 (m, 1H), 7.15-719 (m, 1H), 4.47 (q, J=7.1 Hz, 2H), 2.78 (s, 3H), 1.46 (t, J=7.1 Hz, 3H); MS: m/z 223.0 (MH+).
