Participants

Reaction Steps

To a solution of Example 65C (26.5 mg, 0.077 mmol) in tetrahydrofuran (0.5 mL)/methanol (0.5 mL) was added 2N NaOH (77 μL, 0.154 mmol). The reaction mixture was stirred at room temperature overnight, and neutralized with 2N HCl (0.154 mmol). It was purified by reverse phase HPLC C-18 column, eluting with a 5-100% CH3CN gradient in 10 mM ammonium acetate(aq.)) to provide the title compound as a white solid (10 mg, 40% yield). 1H NMR (300 MHz, DMSO-d6) δ 8.42 (s, 1H), 8.31 (s, 2H), 5.31 (s, 1H), 4.37 (d, J=5.43 Hz, 1H), 2.49 (s, 3H), 2.48-2.50 (m, 1H), 1.26-2.13 (m, 9H). MS (ESI) m/z 330 (M+H)+.
