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.
A solution of the product of EXAMPLE IF (500 mg, 1.40 mmol), 2-methoxy-4-(4- methylpiperazin- 1 -yl)aniline (321 mg, 1.68 mmol) and ^-toluenesulfonic acid (20 mg, cat.) in ?-butanol (10 mL) was heated at 100C for 18 hours. After cooling, the mixture was poured into saturated aqueous sodium bicarbonate (100 mL) and the solution was extracted with ethyl acetate (3 x 50 mL). The combined organic layers were dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by flash chromatography on silica gel (200-300 mesh) eluting with 20/1 dichloromethane/methanol to afford the title compound. MS: 272.2 (M/2+ H+)., 122833-04-9
122833-04-9 2-Methoxy-4-(4-methylpiperazin-1-yl)aniline 20136253, apiperazines compound, is more and more widely used in various fields.
