実験手順
N-Cyclopropyl-3-(7-hydroxy-1-oxoisoquinolin-2(1H)-yl)-4-methylbenzamide (0.16 g), 2-dimethylaminoethyl chloride hydrochloride (87 mg), potassium carbonate (0.65 g), and sodium iodide (7 mg) were stirred in acetone (8 ml) at 60° C. for 16 hours. The reaction mixture was filtered, the solids washed with acetone, and the filtrate was concentrated. The residue was dissolved in ethyl acetate and washed with 2N NaOH solution, brine, dried (magnesium sulfate) and concentrated. Purification by column chromatography on a silica column eluting with 10% methanol/ethyl acetate+1% aqueous ammonia solution gave N-cyclopropyl-3-[7-[2-(dimethylamino)ethoxy]-1-oxoisoquinolin-2(1H)-yl]-4-methylbenzamide (0.137 g) as a white solid; NMR Spectrum: (DMSOd6) 0.57 (m, 2H), 0.69 (m, 2H), 2.10 (s, 3H), 2.23 (s, 6H), 2.68 (t, 2H), 2.85 (m, 1H), 4.19 (m, 2H), 6.72 (d, 1H), 7.21 (d, 1H), 7.41 (d, 1H), 7.49 (d, 1H), 7.68 (s, 1H), 7.71 (d, 1H), 7.75 (s, 1H), 7.88 (d, 1H), 8.43 (d, 1H): Mass Spectrum: M+H+ 406.
