As a common heterocyclic compound, it belongs to phthalazine compound, name is 6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, and cas is 1242156-59-7, its synthesis route is as follows.
Step 2. In a 25 mL container, 1-(3-bromo-2-formylphenyl)-1H-pyrazole-3-carbonitrile (50 mg, 181 mumol, Eq: 1.00), 6-tert-butyl-8-fluorophthalazin-1(2H)-one (79.8 mg, 362 mumol, Eq: 2) and copper (I) iodide (69.0 mg, 362 mumol, Eq: 2.00) were combined with DMSO (2.00 ml) to give a yellow suspension. Sodium bicarbonate (38.0 mg, 453 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, 12 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-oxophthalazin-2(1H)-yl)-2-formylphenyl)-1H-pyrazole-3-carbonitrile (19 mg, 25%).
1242156-59-7, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,1242156-59-7 ,6-(tert-Butyl)-8-fluorophthalazin-1(2H)-one, other downstream synthetic routes, hurry up and to see
