Procedure

A solution of 4-azido-5-fluoropyridine-3-carbaldehyde (10.0 g, 60.0 mmol) and 4-bromo-2,6-dichlorophenylamine (14.4 g, 60.0 mmol) in DCM (200 mL) was cooled to 0° C., under an atmosphere of nitrogen. Triethylamine (25 mL, 180 mmol) was added, followed by dropwise addition of titanium (IV) chloride solution (1 N in DCM, 36 mL, 36 mmol). The reaction mixture was stirred at 0° C. then allowed to reach room temperature overnight. The resultant mixture was concentrated under reduced pressure and the residue was suspended in toluene and filtered through a pad of Celite®. The filtrate was concentrated under reduced pressure to afford the title compound (quantitative yield). This was used in the next step without further purification.
