Procedure

17.5 g of 2-[p-(2,4-dichlorobenzyl)-phenoxi]-propionic acid ethyl ester were refluxed for 2 hours with a solution of 2.5 g of caustic soda in 100 ml of methanol. After cooling, 100 ml of water were added and the mixture was acidified with 2n hydrochloric acid. The propionic acid liberated precipitated in the form of a colorless oil which, on cooling in icewater, solidified to become a colorless wax-like mass. The yield is 15.3 g. ##STR11##
