Participants

Reaction Steps

A mixture of 24.5 g of 4-Hexadecyloxyphenoxyacetic acid methyl ester 10.14 g of potassium hydroxide in 10 ml of water and 250 ml ethyl alcohol is refluxed for 3 hours then allowed to stand at 50° for 18 hours. The mixture is poured into dilute hydrochloric acid and extracted with chloroform. The organic layer is evaporated to a residue which is crystallized from hexane:carbon tetrachloride to give 13.7 g of the desired product as a white solid, m.p. 125°-127° C.
