To a suspension of compound (ii) (3 mg, 0.007 mmol) and potassium carbonate (3 mg, 0.022 mmol) in DMF (0.25 mL) was added iodomethane (3 μL, 0.048 mmol) and the reaction was stirred at 60° C. for 45 min. The mixture was concentrated to dryness and the residue was purified by reverse phase flash column chromatography eluting with ACN/water (5-100%) to afford Compound (55) as a white solid (2 mg, 65%). ESI-MS m/z calculated for [M+H]+: 473.2; found: 473.2; 1H NMR (400 MHz, Acetone) δ 7.86 (d, J=0.5 Hz, 1H), 7.64 (brs, 1H), 7.62-7.56 (m, 2H), 7.42 (s, 1H), 7.14-7.06 (m, 2H), 3.99-3.85 (m, 5H), 3.71-3.62 (m, 2H), 3.59 (t, J=5.2 Hz, 1H), 3.18 (s, 3H), 2.96 (d, J=4.7 Hz, 3H), 2.52-2.42 (m, 1H), 1.91-1.73 (m, 2H), 1.11-0.94 (m, 3H), 0.64-0.53 (m, 1H).
