Procedure

The product from Example 66B (285 mg, 1.48 mmol) in diethyl ether (10 mL) was treated with the product from Example 61A. The mixture was filtered and the filter cake purified by chromatography (95:5 CH2Cl2—MeOH, eluant) to provide that title compound as a white solid. The corresponding di-hydrochloride salt was prepared using methanolic HCl to afford a yellow solid (505 mg, 78%). 1H NMR (300 MHz, DMSO-d6) δ 9.26 (s, 1H), 8.67 (s, 1H), 8.52-8.55 (m, 1H), 8.32 (dd, J=7.8 Hz, 1.1 Hz, 1H), 7.92 (d, J=6.1 Hz, 1H0, 7.73 (d, J=8.2 Hz, 1H), 7.60 (m, 1H), 7.23 (d, J=8.8 Hz, 1H), 6.92-6.96 (m, 3H), 4.26 (d, 5.4 Hz, 2H), 3.72-3.75 (m, 4H), 3.06-3.12 (m, 4H); MS (ESI+) m/z 363 (M+H)+.
