Procedure
A mixture of EXAMPLE 149A (36 mg), 1-chloro-4-iodobutane (0.043 ml) and cesium carbonate (116 mg) in N,N-dimethylformamide (2 ml) was stirred at room temperature overnight. The inorganic salt was filtered off. To the N,N-dimethylformamide solution was added morpholine (0.2 ml) and the resulting mixture was heated at 60° C. for 5 hours. The reaction mixture was concentrated and the residue was purified by RPHPLC (mobile phase: 10%-100% acetonitrile in 0.1% TFA aqueous solution during 60 min) on a C18 column to give ethyl 3-(2-isopropylphenyl)-5-(4-morpholinobutoxy)-1-(3-(naphthalen-1-yloxy)propyl)-1H-indole-2-carboxylate. This ester was hydrolyzed with aqueous NaOH in a mixture of tetrahydrofuran and methanol to provide the title compound. 1H NMR (400 MHz, dimethyl sulfoxide-d6) δ 9.52 (s, 1H), 8.20 (d, J=8.29 Hz, 1H), 7.87 (d, J=7.98 Hz, 1H), 7.59 (d, J=8.90 Hz, 1H), 7.43-7.57 (m, 3H), 7.30-7.43 (m, 3H), 7.14-7.23 (m, 1H), 7.06 (d, J=7.36 Hz, 1H), 6.89 (dd, J=9.05, 2.30 Hz, 1H), 6.85 (d, J=7.67 Hz, 1H), 6.43 (d, J=2.45 Hz, 1H), 4.88 (t, J=7.21 Hz, 2H), 4.15 (t, J=5.83 Hz, 2H), 3.89-4.03 (m, J=11.97 Hz, 2H), 3.75-3.89 (m, 2H), 3.55-3.70 (m, 2H), 3.07-3.17 (m, 2H), 3.02 (s, br, 2H), 2.61-2.78 (m, 2H), 2.23-2.45 (m, 2H), 1.60-1.85 (m, 4H).
