関与物質

反応手順

To 4 ml of dioxane were added 6.0 g of 4'-hydroxypropiophenone. 6.8 Grams of bromine were added dropwise to the mixture with stirring at room temperature, and the reaction liquid was stirred for an additional 5 minutes. To the reaction liquid were then added 8.1 g of 4-benzylpyridine, 100 ml of methanol and 3.3 g of anhydrous sodium acetate, and the mixture was refluxed under heating for 5 hours. After refluxing the mixture, the reaction mixture was worked up in the same manner as described in Example 46, whereby 12.3 g (79.9%) of ifenprodil were obtained as white crystals.
