With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3482-14-2,Isoquinolin-8-ol,as a common compound, the synthetic route is as follows.
Synthesis of 8-propoxy-isoquinoline (2) To a solution of 8-hydroxy-isoquinoline (1) (1.7 g, 11.7 mmol) in DMF (20 ml) at 0 C was added NaH (940 mg, 23.4 mmol, 2.0 eq.). The mixture was stirred for 30 min. Bromopropane (1.6 ml, 17.6 mmol, 1.5 eq.) was then added. The reaction was allowed to warm to RT and was stirred for 1 h. The reaction was diluted with EtOAc and washed with water. The organic layer was dried over MgSO4 and concentrated. The residue was purified by flash chromatography (cyclohexane/EtOAc 10/0 to 8/2) to afford 1.4 g (63 %) of 8-propoxy-isoquinoline (2) as red oil. 1H NMR (300 MHz,DMSO-d6) delta : 9.66 (s, 1H), 8.52 (d, J = 5.8 Hz, 1H), 8.17 (d, J = 7.1 Hz, 1H), 7.8 (t, J = 8.1 Hz, 1H), 7.65 (d, J = 8.2 Hz, 1H), 7.28 (d, J = 7.8 Hz, 1H), 4.02 (s, 3H)., 3482-14-2
3482-14-2 Isoquinolin-8-ol 135441711, aisoquinoline compound, is more and more widely used in various fields.
