1242156-59-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, cas is 1242156-59-7,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
Example 109a 3-Bromo-5-(6-tert-butyl-8-fluoro-1-oxo-1,2-dihydrophthalazin-2-yl)pyridine-4-carbaldehyde 109a A sealed tube equipped with a magnetic stirrer was charged with 6-tert-butyl-8-fluoro-1,2-dihydrophthalazin-1-one 101h (220 mg, 1.0 mmol), 3,5-dibromopyridine-4-carbaldehyde (530 mg, 2.0 mmol), CuI (190 mg, 1.0 mmol), 4,7-dimethoxy-1,10-phenanthroline (244 mg, 1.0 mmol), Cs2CO3 (652 mg, 2.0 mmol) and dioxane (8 mL). After three cycles of vacuum/argon flush, the mixture was heated at 110 C. for 5 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica gel column chromatography eluting with ethyl acetate/petroleum ether (1:3, V/V) to afford 109a (118 mg, 29.3%) as a solid. LCMS: [M+H]+ 406
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, 1242156-59-7
