13130-79-5, 1-Bromoisoquinolin-3-amine is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of Pd(OAc)2 (0.0403 mmol) and triphenylphosphine (0.201 mmol) in toluene (13.0 ml_) was stirred at rt under an inert atmosphere for 10 min. After that period, commercially available 3-amino-1 -bromoisoquinoline (1.34 mmol, 300 mg), anhydrous K2CO3 (2.02 mmol), and commercially available 4-methoxybenzeneboronic acid (2.69 mmol) were sequentially added. The resulting mixture was heated at 100 C in a sealed vial under an inert atmosphere overnight. After being cooled to rt, the mixture was diluted with water and extracted with EtOAc. The combined organic phases were dried over anhydrous sodium sulphate and concentrated under vacuum. The crude residue was purified by flash column chromatography over silica gel, eluting with a 7:3 petroleum ether/EtOAc mixture as the eluent to afford intermediate V (97% yield). [1H-NMR (CDC ) d (ppm): 3.89 (s, 3H), 4.48 (bs, 2H), 6.72 (s, 1 H), 7.04 (AA?XX?, 2H, JAX = 8.8 Hz, JAAVXX? = 2.5 Hz), 7.17 (ddd, 1 H, J = 8.6, 6.7, 1.2 Hz), 7.47 (ddd, 1 H, J= 8.4, 6.7, 1.2 Hz), 7.57 (d, 1 H, J = 8.4 Hz), 7.62 (AA?XX?, 2H, JAX = 8.8 Hz, JAAVXX = 2.5 Hz), 7.90 (dd, 1 H, J= 8.5, 0.8 Hz).]
