Versuchsvorschrift

To a solution of 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-iodo-7-methoxy-3,4-dihydroisoquinolin-1(2H)-one (53c, 300 mg, 0.568 mmol) in NMP (8 mL, dry) was added CuCN (152 mg, 1.705 mmol) at room temperature. The resulting mixture was stirred at 190° C. for 3 hours. The mixture was cooled to room temperature and H2O (20 mL) was added to the mixture. The mixture was diluted with EtOAc (5×20 mL). The combined organic layers were washed with brine (3×20 mL), dried over Na2SO4, and concentrated under vacuum to give a residue, which was purified by column chromatography (petroleum ether/EtOAc, 3:1) to obtain 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-7-methoxy-1-oxo-1,2,3,4-tetrahydroisoquinoline-8-carbonitrile (53d, ˜0.568 mmol, 100%) as a yellow solid.
