122833-04-9, 2-Methoxy-4-(4-methylpiperazin-1-yl)aniline is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 2-Chloro-4-(3-nitrophenoxy)quinazoline (3, 500 mg , 1.66 mmol) in isopropanol (IPA) (20 mL) was added p-TSA (315 mg, 1.66 mmol) and compound 4 (367 mg, 1.66 mmol). The solution was then stirred at 100 C for 30 min. The reaction was monitored by TLC. After completion of the reaction, the reaction mixture was concentrated to dryness, diluted with water, and extracted with ethyl acetate. The organic extract was dried over anhydrous sodium sulfate and evaporated under reduced pressure. The resultant crude product was purified by columnchromatography using 2-5% CH3OH-DCM to afford N-(2-methoxy-4-(4-methylpiperazin-l -yl) phenyl)-4-(3-nitrophenoxy) quinazolin-2-amine as yellow solid (5, 0.28 g, 34.6 %). NMR (CDClj): delta 8.30-8.10 (m, 3H), 7.80-7.60 (m, 4H), 7.40-7.20 (m, 2H), 6.50 (s, 1 H), 6.40 (bs, 1 H), 3.80 (s, 3H), 3.20-3.00 (m, 4H), 2.70-2.60 (m, 4H), 2.40 (s, 3H).
122833-04-9, The synthetic route of 122833-04-9 has been constantly updated, and we look forward to future research findings.
