With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.694499-26-8,4-((4-Methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)aniline,as a common compound, the synthetic route is as follows.,694499-26-8
5-Bromo-6-methyl – nicotinic acid (0.20 g, 0.93 mmol) and 4-(4-methyl – piperazinyl small-ylmethyl) -3-trifluoromethyl – phenylamine (0.23g, 0.85 mmol ) was dissolved in N, N- dimethylformamide (10 mL), were addedunder ice-cooling 2 – (; 7-aza-benzotriazole) -Nu, Nu, Nu ‘, Nu’- tetramethylhexafluorophosphate (0.39 g, 1.02 mmol) and diisopropylethylamine (0.20 mL,1.27 mmol), and stirring was continued overnight. The reaction mixture waspoured into water, extracted with ethyl acetate, the organic phaserespectively, 5% dilute hydrochloric acid, saturated sodium bicarbonatesolution, washed with water and saturated brine, dried over anhydrous sodiumsulfate, and concentrated under reduced pressure, silica gel columnchromatography to give 5-bromo-6-methyl -N- [4- (4- methyl -piperazin-1-ylmethyl) -3-trifluoromethyl – phenyl] – nicotinamide (yellowsolid, 0.26 g ), yield 65%.
694499-26-8 4-((4-Methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)aniline 46838908, apiperazines compound, is more and more widely used in various fields.
