As a common heterocyclic compound, it belongs to phthalazine compound, name is 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, and cas is 1242156-59-7, its synthesis route is as follows.,1242156-59-7
To a suspension of NaH (60%, 473 mg, 1 1.8 mmol) in DMF (5 mL) was added a solution of 6- tert-butyl-8-fluoro-2H-phthalazin-l-one (which may be prepared as described in Berthel, S. et al. US 20100222325 Column 139; 1.3 g, 5.91 mmol) at 0 C. The mixture was stirred for 5 min at 0 C and heated at 70 C for 30 min under nitrogen. The mixture was cooled to room temperature, a solution of 4-bromo-l-bromomethyl-2-fluoro-benzene (1.74 g, 6.5 mmol) in DMF (3 mL) was added and the mixture was stirred for 1.5 h at room temperature. Cold water (5 mL) was added. The mixture was extracted with EtOAc and the organic extract was dried (Na2S04), and evaporated. The residue was purified by chromatography (silica gel, 20% EtOAc/hexane) to give 2-(4-bromo-2-fluoro-benzyl)-6-tert-butyl-8-fluoro-2H-phthalazin-l-one (1.0 g, 41%) as a yellow solid. MS calcd. for Ci9Hi8BrF2N20 [(M+H)+] 407, obsd. 407.2.
With the complex challenges of chemical substances, we look forward to future research findings about 1242156-59-7,belong phthalazine compound
