Procedure

2-Methoxy-N-methylaniline (7.4 g, 53.8 mmol) and triethylamine (10.9 g, 107.7 mmol) were added to 5-bromo-4-chloro-2-fluoro-benzoyl chloride (Step 21D, 11.7 g, 43.1 mmol) in DCM (200 mL) at 0° C. The mixture was then allowed to warm to rt and concentrated. The mixture was partitioned in water and ethyl acetate. The organic layer was separated, washed with NaHSO4 solution, water and brine, and was dried. After filtration and concentration, the residue was purified via silica gel flash column chromatography eluting with ethyl acetate in hexane (50%) to give 5-bromo-4-chloro-2-fluoro-N-(2-methoxy-phenyl)-N-methyl-benzamide (12.5 g). MS: [M+H]+ 374.0/372.0; tR=2.70 min (method 1)
