Reaction Steps

1.093 g (3.582 mmol) of 5-bromo-3-(2-methoxy-1-phenylvinyl)-2-pyridinylamine was dissolved in 60 ml of anhydrous 1,4-dioxane, 800 μl of 70% aqueous perchloric acid was added and the mixture heated to 100° C. for 13 hours. The mixture was then cooled to room temperature and 3 ml of methylamine was added and the mixture evaporated to dryness. The resulting crude was crystallized from hot ethanol to afford 763 mg (2.79 mmol, 78% yield) of 5-bromo-3-phenylpyrrolo[2,3-b]pyridine as a beige-brown to brown crystalline solid. 1H-NMR (d6-DMSO) δ: 12.19 [1H] s, 8.44 [1H] d, 8.34 [1H] d, 7.97 [1H] d, 7.72 [2H] d(m), 7.45 [2H] t, 7.27 [1H] t(m). MS: m/z [MH+].
