Reaction Steps

To a solution of 2-(2-phenylethyl)-1H-pyrrolo[2,3-b]pyridine-4-carbohydrazide (104 mg, 0.371 mmol) in N,N-dimethylacetamide (1 mL) was added a solution of cyanogen bromide (47 mg, 0.445 mmol) in N,N-dimethylacetamide (0.5 mL) at room temperature, and the resulting mixture was stirred overnight. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate), and recrystallized from N,N-dimethylformamide/water to give the title compound (50 mg, yield 44%) as pale-yellow crystals.
