The product from Example 172B (285 mg, 1.48 mmol) in diethyl ether (10 mL) was treated with an ethereal solution of 5-isocyanatoisoquinoline, causing a white precipitate to form. This precipitate was collected by filtration and purified by chromatography (95:5 CH2Cl2—MeOH, eluant) to provide the title compound. The corresponding di-hydrochloride salt was prepared using methanolic HCl to afford a yellow solid. 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, 1H), 7.73 (d, J=8.2 Hz, 1H), 7.60 (m, 1H), 7.23 (d, J=8.8 Hz, 2H), 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)+.
