Procedure

1-(4-Methoxybenzyl)-5-(5-oxa-6-azaspiro[3.4]oct-6-en-7-yl)-N-(tetrahydro-2H-pyran-4-yl)-1H-pyrazolo[3,4-b]pyridin-4-amine (1.8 gm, 4 mmol) (example 9) was dissolved in trifluoroacetic acid (4.56 gm, 40 mmol) and the reaction mixture was stirred for about 4 hours at room temperature under nitrogen atmosphere. The reaction mixture was diluted with ethyl acetate and sodium bicarbonate solution was added drop wise. It was extracted with ethyl acetate, organic layer was washed with water, brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography.
