Reaction Steps

Hydrogen chloride is bubbled into a solution of 87 (1.5 g, 3.37 mmol) in EtOAc (30 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 to give 1.05 g of the product 88. 1H NMR (DMSO-d6) δ 9.28 (t, 1 H), 8.68 (s, 1 H), 8.15 (s, 1 H), 7.35-7.10 (m, 3 H), 7.10-6.80 (m, 7 H), 6.80-6.50 (m, 4 H), 5.03 (s, 1 H), 4.80-4.45 (m, 2 H); MS: m/z 346 (M++1).
