Reaction Steps

A solution of 4-azido-5-fluoropyridine-3-carbaldehyde (2.86 g, 17.2 mmol) and 2-amino-3-chlorobenzonitrile (2.62 g, 17.2 mmol) in DCM (60 mL) was cooled to 0° C. under an atmosphere of nitrogen. Triethylamine (7.2 mL, 51.6 mmol) was added, followed by dropwise additiona of titanium (IV) chloride solution (1 N in DCM, 10.3 mL, 10.3 mmol). The reaction mixture was stirred at 0° C. for 2 hours, then at room temperature overnight. The resultant mixture was concentrated under reduced pressure and the residue was dissolved in ethyl acetate and filtered through a pad of Celite®. The filtrate was concentrated under reduced pressure and the residue obtained was used in the following step without further purification.
