Reaction Steps

To a 500 milliliter round bottom flask equipped with a water collector, water condenser, magnetic stirrer and drying tube was added 5.38 grams (0.030 moles) of 4-amino-2,3-dihydro-2,2-dimethyl-7-hydroxybenzofuran, 3.91 grams (0.032 moles) of salicylaldehyde and 300 milliliters of ethyl acetate. The resulting reaction mixture was heated to reflux with removal of the first 50 milliliters of distillate, and the remaining mixture allowed to reflux for 1 additional hour with continuous stirring. After the stirring and refluxing period, the reaction mixture was cooled to room temperature, filtered, dried over magnesium sulfate and concentrated under reduced pressure to give 6.15 grams (0.022 moles) of 2,3-dihydro-2,2-dimethyl-4-(2-hydroxybenzylideneamino)benzofuran-7-ol in the form of a dark red oil.
