Reaction Steps

To 2,4-difluoro-phenylamine (42, 10.0 g, 77.4 mmol) in N,N-dimethylformamide (130 mL) were added potassium carbonate (32.1 g, 0.23 mol) and benzyl bromide (21.2 mL, 0.18 mol). The reaction was stirred at room temperature overnight. The reaction was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtrated. The filtrate was concentrated and purified by silica gel column chromatography eluting with 10% ethyl acetate in hexane. The appropriate fractions were combined and concentrated to provide the compound (52, 12.0 g, 50%). MS (ESI) [M+H+]+=310.2.
