Procedure

Dissolve 1.4 gm of the ester of Step A in 15 ml of ethanol and add 15 ml of 20% aqueous sodium hydroxide. Warm gently on a steam bath until complete solution is obtained. Strip to dryness and dissolve in water. Acidify with concentrated hydrochloric acid and separate the precipitate by filtration. Crystallize from methanol to obtain the title product (m.p. 240°-244° C.)
