115761-79-0, 1-(2,4-Difluorophenyl)piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To 48 (26 mg, 0.1 mmol) in DMF (1 mL) was added 2,4- difluorophenylpiperazine (20 mg, 0.1 mmol). The reaction mixture was stirred for 1.5 hours. To the crude mixture was added 2-thiopheneethylamine (14 pL, 0.12 mmol), DIEA (38 pL, 0.22 mmol) and HATU (42 mg, 0.11 mmol). The reaction was stirred overnight at room temperature. The reaction mixture was poured into water and extracted with EtOAc. The combined organic layers were washed with 0.1 N NaOH, 0.1 N HCI, and brine; dried over sodium sulfate and concentrated in vacuo to yield 49 as an oil (49 mg, 94%). HPLC- MS tR = 2.10 min (UV254 nm); mass calculated for formula C24H27F2N3O6S 523.2, observed LCMS m/z 524.4 (M+H) ; purity > 95% (ELSD).
115761-79-0, As the paragraph descriping shows that 115761-79-0 is playing an increasingly important role.
