Versuchsvorschrift
To a 25 mL round-bottomed flask containing 6-bromoisoquinolin-3-ol (500 mg, 2.23 mmol) was added TEA (0.467 mL, 3.35 mmol) and benzyl bromide (0.319 mL, 2.68 mmol) in DMF (10 mL) to give a brown solution. The reaction was heated to 80° C. overnight. After cooling to RT, the reaction mixture was concentrated in vacuo, and taken up in DCM and water. The water was extracted with DCM (2×), and the combined organic fractions were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purify by flash column chromatography (10-30-50% EtOAc/Heptanes), providing the title compound (132 mg, 0.420 mmol, 19% yield). M+1=316.0. 1H NMR (400 MHz, CHLOROFORM-d) δ 8.92 (s, 1H), 7.85 (d, J=1.25 Hz, 1H), 7.74 (d, J=8.78 Hz, 1H), 7.31-7.52 (m, 6H), 6.99 (s, 1H), 5.48 (s, 2H).
