实验过程

To 300 ml of acetone there are added 10 g of 5-bromo-2-hydroxybenzaldehyde (49.7 mmol), 13.7 g of potassium carbonate (99.5 mmol) and 10.1 ml of 4-bromobut-1-ene (99.5 mmol); the reaction mixture is then heated at reflux for 36 hours before being cooled, filtered and evaporated to dryness to yield 4-[5-bromo-2-(but-3-en-1-yloxy)phenyl]-4-hydroxybutan-2-one in the form of an oil.
