Reaction Steps

To a stirred solution of 2-(4-(3-((1-(4-methoxybenzyl)-3-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)amino)benzyl)piperazin-1-yl)ethanol (163) (50 mg, 0.103 mmol) in CHCl3 (10 mL) was added trifluoroacetic acid (6 mL) and the reaction mass heated at 60° C. overnight. After completion of the reaction the solvents were completely distilled off and diluted with water and the pH was adjusted to 9 and extracted with chloroform twice. The combined organic layer was washed with brine solution and dried over sodium sulphate and the solvents were removed and the crude material was passed through 100-200 mesh silica gel, eluting with 10% MeOH/CH2Cl2 obtained pure 2-(4-(3-((3-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)amino)benzyl)piperazin-1-yl)ethanol 164 as a pale yellow colored solid (6 mg). MS m/z 353.54 (M+H)+.
