Reaction Steps
A mixture of 5-bromo-3-(1-cyclopentyl-2-methoxy-vinyl)-pyridin-2-ylamine (116.9 mg, 0.39 mmol) and perchloric acid (0.1 mL) in dioxane (1 mL) was heated at 80° C. for 2 hrs. Solvents were evaporated and the residue was washed with a solution of 2M sodium carbonate (5 mL). A precipitate was formed and filtered off. It was washed with water and dried to afford the product 5-bromo-3-cyclopentyl-1H-pyrrolo[2,3-b]pyridine (69.8 mg, 67% yield) as a brown solid. MS: m/z 265/266 [MH+].
