반응 단계

A solution of 250 ml of 2-acetylpyridine and 500 ml of N,N-dimethylformamide dimethyl acetal was heated on a steam bath for 6 hours. After concentrating the reaction solution under vacuum, 1 liter of hexane was added to the part crystalline residue. The product was collected as small crystalline particles which were washed with an additional liter of hexane. Air drying was followed by drying at 45° C. under vacuum, leaving 350.7 g of 3-dimethylamino-1-(2-pyridinyl)-2-propen-1-one.
