Thionyl Chloride → 3-iodo-4-methyl-N-(4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)phenyl)benzamide

Participants

Reaction Steps

3-Iodo-4-methylbenzoyl chloride (0.48 g, 1.7 mmol), prepared from the reaction of 3-iodo-4-methylbenzoic acid and SOCl2 (as previously described), was added to a solution of 4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)aniline (0.47 g, 1.7 mmol), N,N-diisopropylethylamine (0.26 g, 2.0 mmol), and a catalytic amount of DMAP in THF (10 mL). After stirring at rt for 2 h, 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 (eluted with 5% MeOH/DCM, MeOH was pre-saturated with ammonia gas), to provide 0.51 g of product as an off-white solid.
