Procedure

HCl in 1,4-dioxane (4 M, 2 mL) was added to a solution of Example 55 (20 mg, 0.03 mmol) in MeOH (0.5 mL). This mixture was stirred at room temperature for 18 hr. The solvents were removed under reduced pressure and the crude product re-dissolved in MeOH/water (1:1, 5 mL). K2CO3 (0.3 g, 7, 2.2 mmol) was added and the mixture heated and stirred at 60° C. for 3 hr before being cooled to room temperature. The mixture was concentrated under reduced pressure and the residue purified by preparative HPLC to yield 351 as a white solid (4 mg, 25%). 1H NMR (400 MHz, CDCl3) δ 9.02 (s, 1H), 7.88 (s, 1H), 7.37-7.28 (m, 1H), 7.08-6.98 (m, 2H), 6.15 (s, 2H), 3.73 (s, 3H), 3.39-3.13 (m, 6H), 2.46-2.34 (m, 1H), 2.22-2.03 (m, 2H), 1.99-1.89 (m, 1H), 1.83-1.78 (m, 1H). LCMS (ES+) m/z 484.0 (M+1).
