Reaction Steps

3-(Trifluoromethyl)piperidine (0.69 g, 4.5 mmol) followed by potassium carbonate (1.25 g, 9.1 mmol) were added to 4,5-dichloro-N-methyl-2-nitroaniline (1.00 g, 4.5 mmol) in DMF (15 mL). The reaction mixture was stirred 5 h at 80° C. and overnight at 70° C. After addition of further 1.5 eq of potassium carbonate the mixture was stirred 2 h at rt and 2 days at 100° C. The reaction mixture was filtered through a pad of ALOX B and concentrated. The crude was purified by chromatography to give the sub-title compound.
