反応手順
In a 500 ml flask, 120 ml of acetonitrile, 13.8 g of 4-hydroxybenzaldehyde, 21.1 g of 2-(2-bromoethyl)-1,3-dioxane, 1.8 g of potassium iodide, and 35.8 g of potassium carbonate were placed and then, reacted at 80° C. for 5 hrs. Thereafter, 200 ml of ethyl acetate was added to the reaction mixture and washed once with a saturated aqueous potassium carbonate solution, distilled water, and saturated saline. The washed organic phase was dried over anhydrous magnesium sulfate and removed solvent, to give 25.6 g of 4-(2-[1,3]-dioxane-2-yl-ethoxy)benzaldehyde.
