With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.122833-04-9,2-Methoxy-4-(4-methylpiperazin-1-yl)aniline,as a common compound, the synthetic route is as follows.
EXAMPLE 30B 7-chloro-5-(2-methoxy-4-(4-methy lpiperazin- l-yl)pheny lamino)py rido[3.4-i/]py ridazin- 4(3H)-one To a solution of EXAMPLE 7K (120 mg, 0.56 mmol) in dioxane (10 mL) was added EXAMPLE 30A (136 mg, 0.6 ] mmol) and NN-diisopropy lethylamine (724 mg, 5.6 mmol) and the mixture was stirred at 120C in a sealed tube for 16 hours. The mixture was cooled to ambient temperature, poured into water (50 mL) and extracted with ethy l acetate (3 * 50 mL). The organic layer was dried over anhydrous sodium sulfate, filtered, concentrated and purified by flash chromatography on si lica gel (200-300 mesh) eluting with 50/1 dichlomethane/methanol to give the title compound. MS : 401 (M + IT)., 122833-04-9
The synthetic route of 122833-04-9 has been constantly updated, and we look forward to future research findings.
