With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.780753-89-1,1-(4-Fluorophenyl)piperazin-2-one,as a common compound, the synthetic route is as follows.

780753-89-1, Example 13 4-[(2,3-Dichlorophenyl)carbonyl]-1 -(4-fluorophenyl)-2-piperazinone (E13); 1-(4-Fluorophenyl)-2-piperazinone (150mg, 0.77 mmol, prepared as described above for Example 12) and lambda/-ethyl-lambda/-(1-methylethyl)-2-propanamine (0.20 ml, 1.16 mmol) were added together in dichloromethane (4 ml) at O0C. Subsequently 2,3- dichlorobenzoyl chloride (178 mg, 0.85 mmol) was added portionwise. The mixture was left under argon and in an icebath and allowed to return to room temperature whilst being stirred constantly overnight. Dichloromethane and aqueous 3N citric acid were then added and the mixture was extracted into dichloromethane (x2). The dichloromethane layers were combined and washed sequentially with water (x1 ), saturated aqueous sodium hydrogen carbonate (x1 ), water (x1 ), and brine (x1 ), and then dried over magnesium sulphate. The solvent was evaporated in vacuo to give 4-[(2,3-dichlorophenyl)carbonyl]-1-(4-fluorophenyl)-2-piperazinone (224 mg) as a white solid. LC/MS [M+H]+ = 367, retention time = 2.62 minutes.

As the paragraph descriping shows that 780753-89-1 is playing an increasingly important role.

780753-89-1, 1-(4-Fluorophenyl)piperazin-2-one is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 12^{^-Chloro-S-ttrifluoromethylJphenylJcarbony^-i^-fluorophenyl)^- piperazinone (E12); A solution of 1-(4-fluorophenyl)-2-piperazinone (100 mg, 0.52 mmol, prepared as described below), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (158 mg, 0.82 mmol), and lambda/,lambda/-dimethyl-4-pyridinamine (252 mg, 2.06 mmol) in dichloromethane (4 ml) was stirred at room temperature under argon. 2-Chloro-3- (trifluoromethyl)benzoic acid (116 mg, 0.52 mmol) was added portionwise and the mixture was left overnight. Dichloromethane and aqueous 3N citric acid were then added and the mixture was extracted into dichloromethane (x2). The dichloromethane layers were combined and washed sequentially with water (x1 ), saturated aqueous sodium hydrogen carbonate (x1 ), water (x1 ), and brine (x1 ), and then dried over magnesium sulphate. The solvent was evaporated in vacuo and the crude product was purified by flash-silica gel chromatography, eluting with 30-70percent ethyl acetate in isohexane, to give 4-{[2-chloro-3-(trifluoromethyl)phenyl]carbonyl}-1- (4-fluorophenyl)-2-piperazinone (101 mg) as a white solid. LC/MS [M+H]+ = 401 , retention time = 2.70 minutes.

780753-89-1, The synthetic route of 780753-89-1 has been constantly updated, and we look forward to future research findings.
