Procedure

Reflux 90 gm. of the crude methyl o-(p-bromophenoxymethyl)benzoate from Step B for 1 hour in a mixture of 500 cc. of methanol and 250 cc. of 10% aqueous sodium hydroxide. Evaporate the methanol and dilute the resulting aqueous solution with an equal volume of water. Acidify with conc. hydrochloric acid. Separate the solids by filtration, wash with water and dry in vacuo to obtain the title product (m.p. 183°-185° C.).
