Reaction Steps
A mixture of 4-chloro-pyrrolo[2,1-f][1,2,4]triazine-7-carboxylic acid ethyl ester (120 mg), palladium hydroxide on carbon (20%, 40 mg) and sodium acetate (600 mg) in a mixture of ethyl acetate and isopropanol (5/1, 12 mL) was stirred at room temperature under hydrogen atmosphere (balloon pressure) overnight. The resulting mixture was filtered and a CELITE™ pad, the filtrate was evaporated under reduced pressure. The crude residue was purified by flash chromatography to give 45 mg of pyrrolo[2,1-f][1,2,4]triazine-7-carboxylic acid ethyl ester.
