Procedure

In a round bottomed flask equipped with magnetic stirring, reflux condenser, and N2 atmosphere was placed ethanol (500 ml), sodium hydroxide (15.0 g), 4-acetamidophenol of Formula XXIII (30.0 g), and 1-bromo-3-chloropropane of Formula XXII (47.0 g) and the mixture was refluxed overnight. Upon cooling off-white crystals were deposited and then collected. The mother liquor was evaporated to dryness and dissolved in CH2Cl2 then washed with H2O, dried, and concentrated to 50 ml. A second crop of crystals were deposited. These were combined with the first crop of crystals and recrystallized from ethanol to give colorless crystals (20.3 g), mp 128°-130° C.
