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
Example 103b 2-(6-tert-Butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-4-chloronicotinaldehyde 103b Into a solution of 2-bromo-4-chloronicotinaldehyde 103a (446 mg, 2.05 mmol), 6-tert-butyl-8-fluorophthalazin-1(2H)-one 101h (300 mg, 1.36 mmol) in dioxane (50 mL) was added KAcO (267 mg, 2.72 mmol), CuI(259 mg, 1.36 mmol), and 4,7-dimethoxy-1,10-phenanthroline (327 mg, 1.36 mmol). After bubbling nitrogen through the resulting solution for 30 min, the mixture was stirred at 90 C. for 10 h. It was allowed to cool down to room temperature and H2O (100 mL) was added. The aqueous layer was separated and extracted with ethyl acetate (2*200 mL). The combined organic layer was washed with brine (100 mL) and dried over sodium sulfate. The drying agent was removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified on flash column eluting with 10:1 PE/EA to afford 103b (120 mg, 25%). LCMS: [M+H]+ 360. 1H NMR (500 MHz, CDCl3) delta 10.36 (s, 1H), 8.69 (d, J=5.5, 1H), 8.28 (d, J=2.0, 1H), 7.28-7.56 (m, 3H), 1.49 (s, 9H)
With the rapid development of chemical substances, we look forward to future research findings about 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one
