C. 4-[[4-[(4-methyl-1-piperazinyl)methyl]phenyl]amino]-7-(trifluoromethyl)quinoline A solution of 4-chloro-7-trifluoromethylquinoline (400 mg, 0.0018 M), 1-methyl-4-[(4-aminophenyl)methyl]piperazine (400 mg, 0.0019 M) and 1.4 ml of ethanolic hydrogen chloride in 10 ml of ethanol is heated to reflux, under nitrogen for 15 minutes. The reaction mixture is quenched with ice, neutralized with aqueous 10% sodium hydroxide and extracted with methylene chloride. The methylene chloride solution is washed with water, saturated sodium chloride solution, dried over anhydrous sodium sulfate and concentrated to a white solid. This solid, after recrystallization from ethyl acetate, gives 250 mg (32%) of white crystalline 4-[[4-[(4-methyl-1-piperazinyl)methyl]phenyl]amino]-7-(trifluoromethyl)quioline of melting point 218-220 C. Anal. Calcd. for C22 H23 F3 N4: Calcd. C, 65.98; H, 5.79; H, 13.99. Found C, 64.82; H, 5.98; N, 13.44.

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, A solution of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (154 mg, 0.605 mmol), TBTU (232 mg, 0.725 mmol), 4-[(4-methylpiperazin-1-yl)methyl]aniline (150 mg, 0.725 mmol) and DIPEA (0.155 mL, 0.907 mmol) inDMA (7 mL) was let under stirring at rt overnight. The mixture was diluted with EtOAc, washed with a saturated solution of NaHCO3, water and brine, dried over Na2SO4, filtered and taken to dryness under reduced pressure. After treatment with Et20, the solid was filtered and used without any further purification.HRMS (ESI+): calcd. for 025H35BN303 [M + H] 436.2766; found 436.2762.
