694499-26-8, 4-((4-Methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)aniline is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
694499-26-8, A solution of 2 ml trimethylaluminium (2 M in toluene, 4 mMol) is added to a stirred solution of 355 mg (1.3 mMol) 4-(4-methyl-piperazin-1-ylmethyl)-3- trifluoromethyl-phenylamine in 20 ml toluene at 10 0C under an argon atmosphere. After 1 h at r t, a solution of 436 mg (1.3 mMol) 6-(6-acetylamino- pyrimidin-4-ylmethyl)-naphthalene-1-carboxylic acid methyl ester (Step 9.2) in 5 ml THF is added and the reaction mixture is heated at 90 0C for 45 min. After cooling to 5 0C, a solution of sat. aqueous ammonium chloride (50 ml) is added dropwise. The mixture is poured into EtOAc and filtered over hyflo. The separated aq. phase is extracted with EtOAc. The combined organic phases are washed with water and brine, dried (Na2SO4) and concentrated. The crude product is purified by chromatography (SiO2, CH2CI2 / EtOH/ NH3 90:9:1) and is recrystallised from hot EtOAc and hexane to afford the title compound as a colourless solid: m.p.: 202-2040C.
As the paragraph descriping shows that 694499-26-8 is playing an increasingly important role.
