Reaction Steps

To 5-Bromo-pyridine-2-carbaldehyde (52, 1.00 g, 5.38 mmol) in acetonitrile (50.0 mL) were added p-chloroaniline (53, 0.686 g, 5.38 mmol), triethylsilane (6.00 mL, 0.0376 mol) and trifluoroacetic acid (3.00 mL, 0.0389 mol). The reaction was heated to reflux for 3 hours. The reaction was concentrated, poured into water and then 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 20% ethyl acetate in hexane to give a white solid (54, 0.75 g, 47.0%).
