Reaction Steps

A mixture of 1-chloro-6-(2-dimethylamino-benzooxazol-5-yloxy)-4-hydroxy-isoquinoline-3-carboxylic acid butyl ester (115 mg, 0.25 mmol), tris(dibenzylideneacetone)dipalladium(0) (12 mg, 0.01 mmol), 1,1′-bis(diphenylphosphino)ferrocene (14 mg, 0.02 mmol), zinc cyanide (18 mg, 0.15 mmol), zinc (2 mg, 0.03 mmol) and dimethylacetamide (0.6 mL) was stirred at 120° C. for two hours before it was cooled to room temperature, partitioned between ethyl acetate and water, filtered. The filtrate was washed with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel with a gradient of ethyl acetate and dichloromethane to give the title compound as a white solid (53 mg): MS: (+) m/z 447.00 (M+1); (−) m/z 445.20 (M−1).
