With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.262368-30-9,N-(4-Aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide,as a common compound, the synthetic route is as follows.
To a suspension of methyl (Z)-1-acetyl-3- (ethoxy(phenyl)methylene)-2-oxoindoline-6-carboxylate (6) (500 mg, 1.368 mmol) in DMF (3.5 mL) was added N-(4-aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide (14) (395 mg, 1.505 mmol, 1.1 equiv.) at room temperature. After heating the reaction mixture at 80 oC for 1 h, it was allowed to cool to RT. Piperidine (297 muL, 3.010 mmol, 2.2 equiv.) was then added and stirred for 2 h. Volatiles were removed in vacuo and water was added to the obtained residue and stirred for 15 min. Precipitate was then filtered under suction and cake was washed with water, then with minimum amount of cold methanol, and then ether. The obtained product was purified by column chromatography (neutral Al2O3, 0-10% methanol in CH2Cl2) to afford 532 mg (72%) of target molecule 15. Major conformer 1H NMR (400 MHz, DMSO-d6): delta 12.22 (s, 1H), 10.98 (s, 1H), 7.66-7.47 (m, 5H), 7.42 (s, 1H), 7.24-7.09 (m, 3H), 6.89 (d, J = 8.0 Hz, 2H), 5.83 (d, J = 8.0 Hz, 1H), 3.77 (s, 3H), 3.06 (s, 3H), 2.69 (s, 2H), 2.34-2.06 (brs, 8H), 2.10 (s, 3H). HRMS m/z found 540.2606, calcd for C31H34N5O4 [M+H]+ 540.2605.
262368-30-9, The synthetic route of 262368-30-9 has been constantly updated, and we look forward to future research findings.
