Procedure

To a stirred solution of ethyl 3-(3-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)benzoate (119) (10 mg, 0.142, 1 eq) in ethanol (5 mL) was added 4N sodium hydroxide solution (4 mL) and the reaction mixture was stirred at room temperature for 4 hrs. After completion of the reaction the solvents were distilled off and diluted with water and the pH adjusted to 4 and extracted into chloroform. The organic layer was dried over sodium sulphate and the solvents were removed to get the compound 3-(3-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)benzoic acid 120 and this was further titrated with hexane and diethyl ether to get 15 mg of 120.
