Reaction Steps
To a solution of 0.5 g 2-(4-aminophenoxy)-2-methylpropionic acid in 5 ml 2N NaOH, 0.70 ml 3,5-dichlorobenzoyl chloride was dropwise added with stirring 5 ml additional 2N NaOH was gradually added to keep the PH strongly alkaline during the reaction. After 1 hour stirring, the reaction product was acidified with HCl. The white precipitate was recrystallized from aqueous isopropanol to give 1.4 g (76%) of fine crystals MP 206-207°.
