Electric Literature of 82998-57-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 82998-57-0 as follows.
Step 4. 3-Iodo-4-methyl-N-(4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl) phenyl)benzamide 3-Iodo-4-methylbenzoyl chloride (1.06 g, 3.8 mmol), prepared from the reaction of 3-iodo-4-methylbenzoic acid and SOCl2, was added to a solution of 4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)aniline (1.00 g, 3.6 mmol), Et3N (0.36 g 3.6 mmol), and a catalytic amount of DMAP in THF (20 mL). After stirring at rt for 2 hrs, the reaction was quenched with water. EtOAc was added and the layers separated. The combined organic layers were concentrated to dryness and purified by silica gel chromatography (eluent: 5% MeOH in CH2Cl2, MeOH was added 0.5% Et3N) to provide the desired product as an off-white solid (67.2%, 1.25 g). 1H NMR (300 MHz, CDCl3) delta: 8.29 (1H, s), 8.00 (1H, s), 7.85 ((1H, m), 7.73-7.76 ((2H, m), 7.31-7.34 ((1H, d, J=9.0 Hz), 3.64 (2H, s), 2.53 (8H, brs), 2.49 (3H, s), 2.33 (3H, s).
According to the analysis of related databases, 82998-57-0, the application of this compound in the production field has become more and more popular.
