With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.22246-02-2,6-Chloro-3,4-dihydroisoquinolin-1(2H)-one,as a common compound, the synthetic route is as follows.
[B] [5-(6-Chloro-1-oxo-3,4-dihydro-1H-isoquinolin-2-yl)-pyridin-3-yl]-acetic acid (5-Bromo-pyridin-3-yl)-acetic acid methyl ester (230 mg, 1.0 mmol), 6-chloro-3,4-dihydro-2H-isoquinolin-1-one (intermediate A-2) (182 mg, 1.0 mmol), CuI (40 mg, 0.21 mmol), Cs2CO3 (650 mg, 2.0 mmol) and (+)-(1S,1S)-1,2-diaminocyclohexane (0.1 mL, 0.8 mmol) were dissolved in dioxane (4.0 ml) and the resulting reaction mixture was heated at 150 C. for 2 hours before it was poured into H2O (20 mL) and extracted with EtOAc (2*100 mL). The combined organic layer was washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give a crude product (230 mg, 72.5%) as light brown oil. MS: 317.1 (M+H+)., 22246-02-2
22246-02-2 6-Chloro-3,4-dihydroisoquinolin-1(2H)-one 19375637, aisoquinoline compound, is more and more widely used in various fields.
