実験手順
To a solution of 4-bromoisoquinolin-1-amine (403 mg, 1.81 mmol) in methylene chloride (11 mL) at 0° C. was added N,N-diisopropylethylamine (1.57 mL, 9.03 mmol), followed by acetyl chloride (0.321 mL, 4.52 mmol) dropwise. The mixture was stirred at 0° C. for 10 min then at room temperature for 2 h. The mixture was diluted with DCM (10 mL). Water (20 mL) was added. The organic layer was separated. The aqueous solution was extracted with DCM (10 mL). The combined DCM solutions were dried (Na2SO4). After filtration and concentration, the crude was purified with flash chromatography to give the desired product (470 mg, 85%). 1H NMR (400 MHz, DMSO) δ 8.79 (s, 1H), 8.23 (d, J=8.4, 1H), 8.13 (d, J=8.4, 1H), 8.05 (t, J=7.7, 1H), 7.87 (t, J=7.6, 1H), 2.23 (s, 6H).
