Procedure

To 2,6-difluoropyridine (58, 9.85 g, 0.0856 mol) in N-methylpyrrolidinone (50.0 mL) were added p-chlorobenzylamine (61, 10.5 mL, 8.63 mmol) and N,N-diisopropylethylamine (30.0 mL, 0.172 mol). The reaction was stirred at 90° C. overnight. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 25% ethyl acetate in hexane, then washed with ethyl acetatehexane to give a white solid (536, 10 g, 50%).
