実験手順
To a solution of Example 120D (96 mg, 0.229 mmol) in dichloromethane (2 mL) was added trifluoroacetic acid (2 mL). The resulting solution was stirred at room temperature for about 2 hours, and concentrated in vacuum. The residue was treated with saturated NaHCO3 and extracted with ethyl acetate three times. Combined organic phases were washed with water and brine sequentially, dried over Na2SO4, filtered, and concentrated. The residue was purified by prep-HPLC (Column: BOSTON-C18 20×250 mm 10 μm, eluent: water (0.05% NH4HCO3): acetonitrile, 1:1 to 5:95) (60 mg, 30%) to provide the title compound. LC-LC-MS: m/z (M+H) 323. 1H NMR (400 MHz, CDCl3): δ 7.78-7.80 (m, 1H), 7.35-6.99 (m, 4H), 6.82-6.86 (m, 1H), 6.58-6.61 (m, 1H), 4.77 (s, 1H), 3.00 (b, 3H), 2.69-2.82 (m, 2H), 2.14-2.27 (m, 2H), 1.65-1.95 (m, 2H).
