Procedure
To a solution of 90 mg of ethanol, 40 ml of water and 2.0 g of sodium hydroxide was added 13 g of ethyl 3-[4-(3-dimethylaminopropoxy)phenyl]-1H-pyrazolo[3,4-b]pyridin-1-ylacetate. The mixture was stirred at room temperature for 2 hours. After the completion of the reaction, the reaction mixture was adjusted to pH 7 by dilute hydrochloric acid. The mixture was purified with ion-exchange resin (Diaion HP-20) and recrystallized from hydrous methanol to give 3-[4-(3-dimethylaminopropoxy)phenyl]-1H-pyrazolo[3,4-b]pyridin-1-ylacetic acid, m.p. 221°-223° C.
