Reaction Steps

(E)-ethyl 3-(6-(1,3-dioxoisoindolin-2-yl)hex-1-enyl)-5-fluoro-1-(3-(naphthalen-1-yloxy)propyl)-1H-indole-2-carboxylate (The synthesis of this compound was described in EXAMPLE 160B as an intermediate.) was dissolved in a mixture of tetrahydrofuran and methanol and 5 equivalents of aqueous NaOH (10%) was added. The mixture was heated at 50° C. for 2 days. The reaction mixture was concentrated and the residue was purified by reverse phase HPLC (mobile phase: 0-100% acetonitrile in 0.1% TFA aqueous solution during 60 min) on a C18 column to provide the title compound. 1H NMR (400 MHz, dimethyl sulfoxide-d6) δ 8.18 (d, J=9.21 Hz, 1H), 7.82-7.89 (m, 1H), 7.57-7.70 (m, 4H), 7.42-7.55 (m, 4H), 7.37 (t, J=7.67 Hz, 1H), 7.01-7.14 (m, 2H), 6.84 (d, J=7.67 Hz, 1H), 6.14-6.29 (m, 1H), 4.80 (t, J=7.83 Hz, 2H), 4.13 (t, J=5.68 Hz, 2H), 2.70-2.97 (m, 2H), 2.11-2.37 (m, 4H), 1.41-1.76 (m, 4H).
