Procedure
A solution of ethyl 1-isopropyl-6-(((trifluoromethyl)sulfonyl)oxy)-1H-pyrazolo[3,4-b]pyridine-4-carboxylate (1 g, 2.62 mmol), 3-(hydroxymethyl) phenyl boronic acid (0.438 g, 2.88 mmol) and Pd(PPh3)4 (0.303 g, 0.262 mmol) in 1,4-dioxane (15 mL) was purged with argon for 10 min. Then 2M Na2CO3 solution (4.5 mL, 9.4 mmol) was added to it and again argon was purged through it for 10 min. The reaction mixture was stirred at 100° C. for 1 h and after completion of the reaction water was added to it. Extraction was carried out using EtOAc the combined organic layers were washed with water dried over anhydrous Na2SO4; filtered and concentrated under reduced pressure. The residue was purified by column chromatography to give 0.81 g of target compound.
