実験手順

A mixture of 1-bromo-4-methoxy-8-phenoxy-isoquinoline-3-carboxylic acid methyl ester (1.02 g, 2.63 mmol), copper (I) cyanide (470 mg, 5.25 mmol) and anhydrous dimethylformamide (8.8 mL) was refluxed for ten minutes before it was cooled to room temperature quenched with water and ethyl acetate. The slurry was filtered. The organic layer was washed with water, brine, dried over anhydrous sodium sulfate, concentrated in vacuo and the residue was purified by flash column chromatography on silica gel with a gradient of ethyl acetate and hexanes to give the title compound as a yellow solid (727 mg): MS: (+) m/z 334.83 (M+1).
