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.
2-(4-Bromo-2-fluoro-benzyl)-6-tert-butyl-8-fluoro-2H-phthalazin-1-one To a 20 mL reaction vial with stirbar was added 6-(tert-butyl)-8-fluorophthalazin-1(2h)-one (200.00 mg; 0.91 mmol; 1.00 eq.), 4-bromo-2-fluorobenzyl bromide (267.63 mg; 1.00 mmol; 1.10 eq.), and cesium carbonate (591.75 mg; 1.82 mmol; 2.00 eq.) in ACN (6.00 ml; 114.88 mmol; 126.50 eq.). The reaction vial was sealed and heated to 80 C. overnight. Concentrated and purified by flash chromatography (KP-sil column, 10 g; 5-50% EtOAc/hexanes 15 CV). Concentrated product fractions and dried to afford 218 mg (59%) of the title compound as a orange solid. HPLC: 97% purity. MS: 408 [M+H]+
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
