A solution of 1.0 g (2.71 mmol) of methyl 4-(4-acetyl-3-hydroxy-2-propylphenoxy)methylcinnamate and 569 mg (13.57 mmol) of lithium hydroxide, monohydrate, in a mixture of 9 ml of MeOH, 9 ml of THF and 2 ml of water was stirred at 50° C. for 2 hours. The reaction mixture was cooled to room temperature, diluted with 100 ml of 0.5N HCl solution to give a fine white precipitate. The precipitate was isolated by filtration and recrystallized from ethanol to give 750 mg of the title compound as a fine, white cottony solid; mp 203°-204° C.
