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
Step 2. In a 25 mL container, 1-(3-bromo-2-formylphenyl)-1H-pyrazole-4-carbonitrile (100 mg, 362 mumol, Eq: 1.00), 6-tert-butyl-8-fluorophthalazin-1(2H)-one (160 mg, 724 mumol, Eq: 2) and copper (I) iodide (138 mg, 724 mumol, Eq: 2.00) were combined with DMSO (2.00 ml) to give a yellow suspension. Sodium bicarbonate (76.1 mg, 906 mumol, Eq: 2.5) was added to it. The mixture was heated in a microwave at 120 C. for 1 hr. The reaction mixture was poured into 25 mL sat NH4Cl and extracted with EtOAc (3¡Á25 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The organic layer was concentrated and purified through ISCO flash column chromatography using ethyl acetate (containing 5% methanol) in hexanes (5% to 80% linear gradient in 15 minutes, 24 g silica gel) to give the pure desired product which was triturated with ether in hexanes and filtered to obtain 1-[3-(6-tert-Butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-2-formyl-phenyl]-1H-pyrazole-4-carbonitrile (110 mg, 73%).
1242156-59-7 is used more and more widely, we look forward to future research findings about 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one
