Reaction Steps
To an ice-cooled solution of 3-aminopyridine (6 g, 63.8 mmol) and triethylamine (9.72 mL, 70.2 mmol) in 124 mL of dichloromethane under argon, was carefully added pivaloyl chloride (7.92 mL, 64.4 mmol) in 16 mL of dichloromethane. After the addition was completed, the reaction mixture was stirred at 0° C. for 15 minutes and at room temperature for 18 hours. The mixture was washed with water, aqueous 4% sodium bicarbonate, brine, dried over sodium sulphate and the solvent removed under reduced pressure. The residue was purified by column chromatography on silica flash, using hexane/ethyl acetate (85:15) as eluents, to yield the title compound (8.5 g, 75%) as a white solid.
