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
General procedure: Additional amide analogs were prepared by adding 1.5 equivalents of an amine which will provide the desired substituents into a 1 dram vial (1.5 eq.) along with lithium 5-amino-7- methoxyimidazo[1,2-c]quinazoline-2-carboxylate (30 mg, 0.114 mmol) and a DMF solution (1.0 ml) solution of DIPEA (0.079 ml, 0.454 mmol), shaking the vial for 5 minutes in a Bohdan Miniblock Shaker and then adding 1-propanephosphonic acid cyclic anhydride (50% w/w in EtOAc, 64.7 mul, 0.109 mmol), and continuing to shake the vial at RT overnight. The completed reaction was quenched with 1.0 ml water and the organic layer separated by filtering through a Varian 2 ml Reservior Frit and a Whatman 0.45mum syringe filter to remove emulsion, followed by solvent removal using a Genevac. The crude residue was dissolved in 1.0 ml DMSO and purified by LC/MS.
115761-79-0, The synthetic route of 115761-79-0 has been constantly updated, and we look forward to future research findings.
