Versuchsvorschrift

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) δ: 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).
