Participants

Reaction Steps

A solution of methyl 2-hydroxy-4-[2-(phenethyl)phenethyl]benzoate (0.25 g) in THF (5 ml) and methanol (5 ml) containing aqueous 2N sodium hydroxide (5 ml) was heated under reflux for 2 hours. The reaction mixture was evaporated to small volume and acidified with aqueous 2N hydrochloric acid. The mixture was extracted three times with ethyl acetate (25 ml each time) and the combined extracts were washed with brine and dried over anhydrous magnesium sulphate. The solid obtained on removal of the solvent was crystallised from a mixture of diethyl ether and hexane to give 2-hydroxy-4-[(2-phenethyl)phenethyl]benzoic acid (0.2 g), m.p. 134-7° C.
