Reaction Steps

A mixture of (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.) (270 mg) and hydrazine (0.030 ml) in tetrahydrofuran (1.00 ml) and ethanol (3 ml) was heated at 50° C. overnight and concentrated. The residue was dissolved in tetrahydrofuran and methanol and then aqueous 10% NaOH was added. The resulting was heated at 50° C. overnight and concentrated. The residue was purified by RPHPLC to provide the title compound. 1H NMR (400 MHz, dimethyl sulfoxide-d6) δ 8.17 (dd, J=8.44, 1.07 Hz, 1H), 7.84-7.89 (m, 1H), 7.60 (dd, J=9.21, 4.30 Hz, 1H), 7.41-7.56 (m, 4H), 7.32-7.40 (m, 1H), 7.01-7.11 (m, 1H), 6.84 (d, J=7.06 Hz, 1H), 4.80 (t, J=7.21 Hz, 2H), 4.12 (t, J=5.83 Hz, 2H), 2.94-3.06 (m, 2H), 2.75 (t, J=8.29 Hz, 2H), 2.20-2.35 (m, 2H), 1.43-1.63 (m, 4H), 1.27-1.36 (m, 4H).
