Procedure

A mixture of 4-propionylpyridine (5 g, 36.99 mmol) and dimethylformamide dimethylacetal(10 mL, 75.28 mmol) was heated to reflux overnight. After cooling to room temperature, methanol generated in situ was removed from reaction mixture under reduced pressure, providing a brown color solid. The crude product was purified by column chromatography (silica gel, 3:7 EtOAc/haxane) to give the named compound (5.73 g, 81%) as a brown oil.
