Procedure

The mixture of 23 (340 mg, 1.24 mmol), SnCl2 2H2O (902 mg, 6.22 mmol), HCl (0.33 mL) in EtOH (50 mL) stirred at reflux under a N2 atmosphere for 1 h. The solvent was removed under vacuo, washed with NaOH to PH=14, extracted with CH2C12, dried over Na2SO4 and puried by purified by column chromatography to give 24 (235 mg, 75% yield). 1H NMR (CDCl3, 300 MHz): δ=2.37 (s, 3H), 3.89 (s, 2H), 6.59 (s, 1H), 6.76-6.79 (m, 1H), 7.13 (d, 1H), 7.46-7.49 (m, 2H), 7.53 (d, 1H), 7.73 (s, 1H), 7.79-7.81 (m, 2H). LC-MS: 394.9 (M+1)+.
