67455-41-8, 4-(Piperazin-1-yl)aniline is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
67455-41-8, To a solution of 2-chloro-N-cyclohexyl-9-(tetrahydro-2H-pyran-2-yl)-9H- purin-6-amine (0.50 g, 1.5 mmole) in 7.5 ml toluene was added 4-(piperazin-l-yl)aniline (317 mg, 1.8 mmole) and 2-di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl (63 mg, 0.15 mmole). The reaction mixture was degassed using Argon for 10 min after which Pd(dppf)Cl2 complex with CH2C12 (61mg, 0.075 mmole) was added, followed by sodium t-butoxide (286 mg, 3.0 mmole). The reaction flask was put into a preheated oil-bath at 100 C and stirred overnight. The mixture was cooled to room temperature. To the mixture, water and EtOAc were added. The layers were separated and the aqueous layer was extracted with EtOAc. The combined organic layer was dried over Na2S04 and concentrated. The crude product was purified on a silica gel column, eluted EtOAc, then 10% MeOH in EtOAc, then 20%MeOH in EtOAc to get 480mg (68% yield) of N6-cyclohexyl-N2-(4-(piperazin-l- yl)phenyl)-9-(tetrahydro-2H-pyran-2-yl)-9H-purine-2,6-diamine
As the paragraph descriping shows that 67455-41-8 is playing an increasingly important role.
