Procedure
A mixture of EXAMPLE 580A (90 mg), 3-(bromomethyl)pyridine hydrobromide (47.3 mg) and cesium carbonate (183 mg) in N,N-dimethylformamide (3.5 ml) was stirred at room temperature overnight. The insoluble material was filtered off and the filtrate was concentrated. The residue was suspended in tetrahydrofuran-methanol, and 10% NaOH was added. The resulting mixture was stirred at room temperature overnight and concentrated. The residue was dissolved in a mixture of DMSO and methanol. The solution was purified by reverse phase HPLC (mobile phase: 10%-100% acetonitrile in 0.1% TFA aqueous solution during 60 minutes) to provide the title compound. 1H NMR (400 MHz, DMSO-d6) δ 8.55 (d, J=5.22 Hz, 1H), 8.23-8.28 (m, 1 H), 7.85-7.90 (m, 1 H), 7.80-7.85 (m, 2 H), 7.49-7.57 (m, 3 H), 7.45-7.49 (m, 1 H), 7.38-7.43 (m, 1 H), 7.19 (d, J=7.67 Hz, 1 H), 7.10-7.15 (m, 1 H), 6.92 (t, J=7.67 Hz, 2 H), 5.65 (d, J=17.49 Hz, 1 H), 5.44 (d, J=17.80 Hz, 1 H), 4.26 (t, J=5.98 Hz, 2 H), 3.62 (s, 3 H), 3.35-3.49 (m, 2 H), 2.24-2.32 (m, 2 H), 1.67 (s, 3 H), 1.59 (s, 3 H).
