1242157-15-8, 6-Bromo-8-fluoro-3,4-dihydroisoquinolin-1(2H)-one is a isoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1242157-15-8, To a solution of 6-bromo-8-fluoro-3,4-dihydro-2H-isoquinolin-l-one (CAS 1242157-15-8; 500 mg, 2.05 mmol) in dry THF (20.5 mL) are added ELN (1.4 mL, 10.2 mmol), pyridine (1.3 mL, 16.4 mmol), CU(OAC)2 (818 mg, 4.10 mmol) and cyclopropylboronic acid (CAS 411235-57-9; 528 mg, 6.15 mmol). The reaction mixture is stirred at 70 C overnight. Cyclopropylboronic acid (176 mg, 2.05 mmol) is added and the reaction mixture is stirred at 70 C for 2 h. The reaction medium is quenched with a sat. aq. NaHCCfi solution and extracted with EtOAc. The combined organic layers are dried over MgSCL, filtered and concentrated. The crude material is purified by chromatography on silica gel (eluting with a gradient of 0 to 60% EtOAc in heptane) twice to afford the expected 6-bromo-2-cyclopropyl-8-fluoro-3,4- dihydroisoquinolin- 1 -one. LCMS: MW (calcd): 284.1 ; m/z MW (obsd): 284.2/286.2 (M+H)
As the paragraph descriping shows that 1242157-15-8 is playing an increasingly important role.
