실험 절차

Triethylamine (7.1 mL, 51 mmol) was added to a cooled (0° C.) mixture of 4-azidopyridine-3-carbaldehyde (2.52 g, 17 mmol) and 2-chloro-6-fluoroaniline (2.47 g, 17 mmol) in DCM (60 mL) under nitrogen. Titanium tetrachloride (1 M, 10.2 mL, 10.2 mmol) was then added and the resulting mixture was stirred for 1 hour at 0° C. before warming to room temperature and stirring for a further 4 hours. The reaction mixture was concentrated under reduced pressure. The residue was suspended in toluene and filtered through a pad of Celite®. The filtrate was concentrated to dryness under reduced pressure to afford the title compound as a yellow solid. This crude material was employed in the next step without further purification or analysis.
