763111-47-3, 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
4-(4-Fluoro-3-(piperazin-1-yl-carbonyl)-benzyl)pyridazine-1(2H)one (5) (0.78 g, 2.13 mmol) was added to a 25 ml three-necked flask.Dichloromethane (6.5 ml) and triethylamine (0.52 g, 5.14 mmol) were added, and the mixture was stirred and cooled to 1-10 C.Further, 2-butenyl chloride (268 mg, 2.56 mmol) was added dropwise, and the mixture was warmed to room temperature and stirred for 1 hour.TLC showed the reaction was complete; the reaction mixture was directly concentrated to dryness, and the residue was mixed with water and then stirred for 1 hour and then filtered.Obtained as an off-white solid.The yield was 37%.
As the paragraph descriping shows that 763111-47-3 is playing an increasingly important role.
