70261-82-4, 4-(4-Methylpiperazin-1-ylmethyl)phenylamine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
70261-82-4, A solution [CONTAINING-50%] of propylphosphonic anhydride in N, N-dimethylformamide (Fluka, Buchs, Switzerland; 875 [UL, ~1.] 5 [MMOL)] is added within 20 minutes to a stirred mixture of 4- [METHYL-3- [ [4- (3-PYRIDINYL)-2-PYRIMIDINYL] AMINO]-BENZOIC] acid (306 mg, 1.0 [MMOL),] [4- [ (4-METHYL-] 1-piperazinyl) methyl] benzeneamine (Chem. Abstr. Reg. Number: 70261-82-4; 205 mg, 1.0 [MMOL)] and triethylamine (830 [ZL,] 6.0 [MMOL)] in 8 mL [N, N-DIMETHYLFORMAMIDE.] After stirring for 24 hours at room temperature, the mixture is treated with a saturated aqueous ammonium chloride and extracted three times with ethyl acetate. The solvent is evaporated off under reduced pressure and the residue dried in vacuo. The crude product is crystallised from ethanol-ethyl acetate to give the title compound as a crystalline solid, m. p. [153-155C.]
As the paragraph descriping shows that 70261-82-4 is playing an increasingly important role.
