Reaction Steps

To a solution of 4-(3-cyanophenyl)-1-methoxyisoquinoline (200 mg, 0.73 mmol) in acetonitrile (6 mL) is added sodium iodide (219 mg, 1.46 mmol) followed by chlorotrimethylsilane (186 μL, 1.46 mmol) and the mixture is heated at reflux for 1.5 hr. The cooled reaction is diluted with water (15 mL) and the solids are collected by filtration, washed with water and dried to give 3-(3-methyl-1-oxo-1,2-dihydroisoquinolin-4-yl)benzonitrile (157 mg, 83% yield). 1H NMR (δ ppm) 11.55 (1H, s), 8.22 (1H, d), 7.95 (1H, d), 7.82 (1H, s), 7.72 (1H, t), 7.66 (1H, m), 7.60 (1H, m), 7.47 (1H, t), 6.94 (1H, d), 1.99 (3H, s).
