With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.491-30-5,1-Hydroxyisoquinoline,as a common compound, the synthetic route is as follows.
In a 50 ml. round-bottom flask, isocarbostyril (0.50 g, 3.4 mmol) and phosphorus pentabromide (2.7 g, 9.8 mmol) were heated at 140-145 C for 10 min. The solid melted and lightened in color. The liquid solidified, and the reaction was stirred for an additional 10 min. On completion, the reaction mixture was cooled to room temperature, and ice/H20 (10 ml.) was poured into the flask. The solid precipitate was collected by filtration, washed with H20 (2 x 50 ml_), and dried under vacuum to obtain 860 mg (89% yield) of (1) as a buff-colored solid., 491-30-5
The synthetic route of 491-30-5 has been constantly updated, and we look forward to future research findings.
