Name is Phthalazin-1(2H)-one, as a common heterocyclic compound, it belongs to phthalazine compound, and cas is 119-39-1, its synthesis route is as follows.
To the solution of sodium methoxide (0,0165 mol of Na) in dry methanol (70 ml) was added 2H-phthalazin-l-on (0,0153 mol). The mixture was stirred and refluxed for 30 minutes, then cooled to ambient temperature and bis-tosyl-derivative of 2- methylaminoethanol (0.0230 mol) was added. Afterwards the reaction mixture was heated and refluxed for 10 hours. After cooling to room temperature the product was filtrated and recrystalized. If the product was well soluble in reaction solvent, the solvent was first evaporated and to the residue water (20ml) was added. The aqueous layer was extracted with chloroform (3x20ml). The combined extracts were dried over anhydrous MgSO4 and vacuum concentrated till dryness. The residue was purified by column chromatography (silica gel).4,N-Dimethyl-N-[2-(l-oxo-lH-phthalazin-2-yl)-ethyl]-benzenesulfonamide (compound no 5)
119-39-1, 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.,119-39-1 ,Phthalazin-1(2H)-one, other downstream synthetic routes, hurry up and to see
