実験手順

A mixture of 6-bromoisoquinolin-3-ol (606 mg, 2.70 mmol), silver carbonate (1.5 g, 5.3 mmol), and N,N-dimethylformamide (12 mL) was stirred at room temperature for 16 minutes. Methyl iodide (186 μL, 2.97 mmol) was added and the reaction was left stirring for 18 hours. The reaction was diluted with methanol and filtered through Celite. The filtrate was concentrated and purified by flash column chromatography to give the title compound (90 mg, 14%). +ESI (M+H+1) 240.0; 1H NMR (400 MHz, CDCl3, δ): 8.91 (s, 1H), 7.86 (d, J=1.8 Hz, 1H), 7.73 (d, J=8.8 Hz, 1H), 7.43 (dd, J=8.8, 1.8 Hz, 1H), 6.90 (s, 1H), 4.02 (s, 3H).
