With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34784-05-9,6-Bromoisoquinoline,as a common compound, the synthetic route is as follows.
Reference Example 1Synthesis of 6-aminoisoquinoline (Reference Compound 1)6-bromoisoquinoline that weighed 17.2 g (see WO 2008/077553), 200 mL of 28percent ammonia water and 10.8 g of copper (II) sulfate pentahydrate were put into the autoclave and tightly sealed, and the mixture was then stirred at 190¡ã C. for 6 hours.After cooling to room temperature, the reaction solution was poured into 250 mL of a 10percent aqueous sodium hydroxide solution, followed by extraction with ethyl acetate (100 mL*5).The extract was dried over anhydrous sodium sulfate, filtered, and then concentrated.The obtained crude product was suspended in dichloromethane and then filtered to obtain 10.2 g of the compound of interest as a light brown crystal (85percent).1H-NMR spectrum (CDCl3, delta ppm): 5.54 (br s, 2H), 6.58 (s, 1H), 7.00 (d, J=9.0 Hz, 1H), 7.35 (d, J=5.5 Hz, 1H), 7.75 (d, J=9.0 Hz, 1H), 8.32 (d, J=5.5 Hz, 1H), 8.98 (s, 1H)
34784-05-9, 34784-05-9 6-Bromoisoquinoline 313681, aisoquinoline compound, is more and more widely used in various.
