The product of Example 9A (0.173 g, 0.72 mmol) was coupled with the product of Example 38A (0.267 g, 0.91 mmol) under the catalysis of dichlorobis(triphenylphosphine)palladium(II) (Aldrich, 5.3 mg, 0.007 mmol) and 2-(dicyclohexylphosphino)biphenyl (Strem Chemicals, 7.3 mg, 0.021 mmol) at 150° C. for 10 min. according to the procedure of Example 29A. The title product was purified by preparative HPLC (Xterra™, column, Xterra RP-18 5 μm, 30×100 mm. Eluting Solvent, MeCN/H2O (NH4HCO3, 0.1 M, pH=10) (v. 40/60 to 70/30 over 20 min.) Flow rate, 75 mL/min., uv, 250 nm) as solid. 1H NMR (300 MHz, CD3OD) δ 1.45-1.62 (m, 1H), 1.68-1.92 (m, 2H), 2.00-2.15 (m, 1H), 2.27-2.40 (m, Hz, 1H), 2.75-3.05 (m, 5H), 3.43-3.59 (m, Hz, 1H), 5.22-5.42 (m, Hz, 1H), 7.16-7.24 (m, 1H), 7.28 (d, J=9 Hz, 1H), 7.36-7.44 (m, 1H), 7.45-7.52 (m, 1H), 7.57 (d, J=8 Hz, 1H), 8.02 (dd, J=9, 2 Hz, 1H), 8.17 (t, J=9 Hz, 2H), 8.67 (s, 1H) ppm; MS (DCI/NH3) m/z 371 (M+H)+.
