HCID 11151363Abt-107

Procedure

The product of Example 9A (480 mg, 2 mmol) was coupled with 5-indolylboronic acid (Frontier, 403 mg, 2.5 mmol) according to the procedure of Example 3A. The title product was purified by preparative HPLC (Gilson, column, Symmetry® C-8 7 μm, 40×100 mm. Eluting Solvent, MeCN/H2O (with 0.2% v. TFA) (v. 90/10 to 10/90 over 20 min.) Flow rate, 75 mL/min., uv, 250 nm) as solid (240 mg, yield, 38%). 1H NMR (300 MHz, CD3OD) δ 1.49–1.64 (m, 1H), 1.68–1.93 (m, 2H), 2.00–2.15 (m, 1H), 2.28–2.36 (m, 1H), 2.76–3.05 (m, 5H), 3.43–3.55 (m, 1H), 5.26–5.34 (m, 1H), 6.56 (dd, J=3.4, 1.0 Hz, 1H), 7.25 (d, J=9.2 Hz, 1H), 7.31 (d, J=3.1 Hz, 1H), 7.50 (d, J=8.5 Hz, 1H), 7.74 (dd, J=8.5, 1.7 Hz, 1H), 8.08 (d, J=9.5 Hz, 1H), 8.14 (d, J=1.4 Hz, 1H) ppm. MS (DCl/NH3): m/z 321 (M+H)+.
