6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, cas is 1242156-59-7, it is a common heterocyclic compound, the phthalazine compound, its synthesis route is as follows.,1242156-59-7
To a stirred 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; 100 mg, 0.45 mmol) in DMF (5 mL) were added 2-bromo-6-fluoro-benzaldehyde (available from Aldrich; 101.5 mg, 0.5 mmol), cesium carbonate (325 mg, 0.27 mmol) and methoxytrimethylsilane (0.1 mL, 0.91 mmol). The mixture was heated at 60 C for 4 h, then cooled to room temperature and diluted with water (25 mL). The resulting mixture was extracted with ethyl acetate, dried (Na2S04), filtered, and evaporated. The residue was purified by chromatography (silica gel, 10% EtOAc/hexane) to give 2-bromo-6-(6-tert-butyl-8-fluoro-l-oxo-lH-phthalazin-2-yl)-benzaldehyde (105 mg, 57%) as a yellow gum. MS calcd. for Ci9Hi7BrFN202 [(M+H)+] 404, obsd. 404.
With the rapid development of chemical substances, we look forward to future research findings about 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one
