The reaction of 2,4-dichlorophenol (I) with 2-chloroacetophenone (II) by means of a copper catalyst and sodium hydroxide gives 2-(2,4-dichlorophenoxy)acetophenone (III), which is treated with sulfur in refluxing morpholine yielding 2-(2,4-dichlorophenoxy)phenylthioacetomorpholide (IV). Finally, this compound is hydrolyzed with KOH in refluxing methanol.
