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 mixture of starting material (25 mg, 0.1 mmol), 2-methoxy-4-(4-methylpiperazin-1-yl)benzenamine (22 mg, 0.1 mmol), X-Phos (4.3 mg), Pd2(dba)3 (5.5 mg) and K2CO3 (41.5 mg, 0.3 mmol) in t-BuOH (1.5 mL) was heated at 100 C. in a seal tube for 4 h. Then the reaction was filtered through celite and eluted with dichloromethane. The solvent was removed in vacuo and the residue was purified by ISCO to afford the title compound (24.7 mg)., 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.

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

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

As the paragraph descriping shows that 122833-04-9 is playing an increasingly important role.

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 n-butanol (2 mL) was added compound 4A-3 (30 mg, 0.135 mmol) and compound 5A-3 (48 mg, 0.135mmol), and then p-toluenesulfonic acid (23 mg, 0.132 mmol) was added under stirring. The mixture was heated to 100C and stirred for 5 hours. After TLC indicated the reaction was completed, the reaction mixture was concentrated under reduced pressure to give a crude product, which was further purified and isolated by column chromatography to obtain an off-white solid product, compound I-2 (25 mg, yield 34.3%). 1H NMR (400 MHz, cd3od) delta 8.11 (s, 1H), 8.05 (s, 1H), 7.81 (d, J=5.5 Hz, 1H), 7.57 (d, J=8.6 Hz, 1H), 6.68 (d, J=2.3 Hz, 1H), 6.57 (dd, J=8.7, 2.4 Hz, 1H), 3.83 (s, 3H), 3.42-3.34 (m, 1H), 3.29 (s, 4H), 2.89 (s, 4H), 2.55 (s, 3H), 1.30 (d, J=6.7 Hz, 6H). LCMS: t=0.690 min, 537.2 (M), 538.2 (M+1).

122833-04-9, The synthetic route of 122833-04-9 has been constantly updated, and we look forward to future research findings.
