3-Iodo-p-toluidine → N-(3-Iodo-4-methylphenyl)-4-((4methylpiperazin-1-yl) methyl)-3-(trifluoromethyl)benzamide

Participants

Reaction Steps

To a flask containing 1.0 g (2.67 mmol) of 4-[(4-methyl-1-piperazinyl)methyl]-3-(trifluoromethyl)-benzoic acid (CAS#859027-02-4; prepared according to Asaki, T. et al. Bioorg. Med. Chem. Lett. (2006), 16, 1421-1425), 0.62 g (2.67 mmol) of 3-Iodo-4-methylaniline, 0.77 g (4.0 mmol) of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDAC), and 0.43 g (3.2 mmol) of N-hydroxybenzotriazole monohydrate (HOBt.H2O) was added 5 mL of DCM and 5 mL of triethylamine. The solution was stirred at ambient temperature under an atmosphere of N2 for 3 days, concentrated, and the crude product purified by silica gel chromatography (eluted with 100% EtOAc then 10% MeOH/EtOAc), to provide 0.69 g of product as a white solid.
