PROCEDURE

实验过程

Hydrogen chloride is bubbled into a solution of 83 (0.44 g, 0.91 mmol) in EtOAc (15 mL) for 1 min, and the solution is stirred at RT overnight. The solvent is removed by rotary evaporation, and the residue crystallized from dichloromethane and Et2O give 0.21 g of the product 84. 1H NMR (DMSO-d6) δ 9.40 (s, 1H), 9.14 (t, 1H), 7.88 (s, 1H), 7.20-6.80 (m, 8H), 6.80-6.55 (m, 4H), 5.07 (s, 2H), 4.70-4.50 (m, 2H); MS: m/z 382 (M++1).
