実験手順

Under a nitrogen atmosphere, 1-bromo-4-butylbenzene (2.29 ml, 13.0 mmol) was added to a mixed solution of magnesium (338 mg, 13.9 mmol) and tetrahydrofuran (6.5 ml), and as an initiator, catalytic amount of 1,2-dibromoethane was added, and this was stirred under reflux for 10 minutes. The solution was cooled to 0° C., a tetrahydrofuran solution of 1-isoquinolinecarbonitrile (1.0 g, 6.49 mmol) was added, and was stirred for another 1 hour at room temperature, and at 70° C. for 3 hours. Subsequently, the solution was cooled again to 0° C., concentrated hydrochloric acid (2.56 ml) and methanol (11 ml) were added, and then refluxed for 2 hours. The concentrated residue was dissolved in 5 N sodium hydroxide and toluene, and was filtered through celite. The toluene layer of the filtrate was divided, washed with water, dried over magnesium sulfate, and concentrated. The residue was purified by silica gel column chromatography to give 1.72 g of the title compound.
