Reaction Steps

The crude product of Example 1198 Part A was combined with 2-methylthio-4,5-dihydroimidazole hydriodide (2.71 g, 11.1 mmol) and pyridine (125 mL), and the mixture was heated at 80° C. for 5 h. The mixture was allowed to cool to room temperature and concentrated under vacuum. The residue was purified by flash chromatography (dichloromethane:methanol 80:20) to provide the title product (3.73 g, 75%) as a gum: 1H NMR (DMSO-d6) δ 8.50 (s, 1H), 8.30 (s, 1H), 8.24 (bs, 1H), 7.98 (d, 1H), 7.75 (d, 1H), 4.49 (t, 2H), 4.34 (q, 2H), 3.57 (s, 4H), 3.13 (m, 2H), 2.05 (m, 2H), 1.35 (t, 3H); High resolution mass spectrum (NH3 --CI) calculated (M+H+) 316.1774, found 316.1765.
