Participants

Reaction Steps

To a solution of 100 mg of ethyl 4-(E-2-methyl-2-(4-(3-methyl-2-butenoxy)phenyl)ethenyl)-benzoate in 3 ml of ethanol under argon is added dropwise a solution of 50 mg of potassium hydroxide in 3 ml of ethanol and 1 ml of water. The mixture is stirred at room temperature for 18 hours, cooled and acidified with 3N hydrochloric acid. The resulting precipitate is dissolved in ether, the ether solution washed with saturated aqueous sodium chloride and concentrated to give a solid which is recrystallized from aqueous methanol to give 4-(E-2-methyl-2-(4-(3-methyl-2-butenoxy) phenyl)ethenyl) benzoic acid.
