With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.70261-82-4,4-(4-Methylpiperazin-1-ylmethyl)phenylamine,as a common compound, the synthetic route is as follows.
70261-82-4, To Example 55D (75 mg, 0.198 mmol) and m-chloroperoxybenzoic acid (53.3 mg, 0.238 mmol) was added 2 mL dichlormethane. The reaction was stirred for 15 minutes when 4-((4-methylpiperazin-1-yl)methyl)aniline (48.9 mg, 0.238 mmol) followed by trifluoroacetic acid (0.031 ml, 0.397 mmol). The mixture was stirred at 50 C. for 1 hour, and at room temperature overnight. The mixture was diluted with ethyl acetate, washed with saturated aqueous NaHCO3, water, and brine, dried over MgSO4, filtered and concentrated. The crude material was dissolved in methanol, and treated with 2N HCl in diethyl ether for 1 hour. The mixture was diluted with diethyl ether and filtered. The solid was triturated with 1:1 DMSO/methanol solution, diluted with ethyl acetate, filtered, and dried over high-vacuum to provide the title compound. 1H NMR (501 MHz, DMSO-d6) delta 2.53 (s, 2H) 2.78 (s, 2H) 3.15 (s, 3H) 3.19-3.50 (m, 4H) 3.91 (s, 2H) 7.09 (d, J=1.18 Hz, 1H) 7.47 (d, J=7.58 Hz, 2H) 7.55-7.64 (m, 1H) 7.66-7.74 (m, 2H) 7.80 (d, J=1.66 Hz, 1H) 7.86 (d, J=8.06 Hz, 2H) 9.16 (s, 1H). MS (ESI+) m/z 534.9 (M+H)+.
70261-82-4 4-(4-Methylpiperazin-1-ylmethyl)phenylamine 3153996, apiperazines compound, is more and more widely used in various fields.
