Sodium Carbonate → {3-[3-(2-methoxy-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-b]pyridin-5-yl]-phenyl}-(3-methyl-pyridin-2-yl)-methanol

Participants

Reaction Steps

415 mg (0.87 mmol) of 3-(2-methoxy-phenyl)-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-b]pyridine, 40 mg (49 μmol) of dichloro[1,1′-bis(diphenyl-phoshino)ferrocene]palladium(II) dichloromethane adduct and 240 mg (0.86 mmol) of (3-bromo-phenyl)-(3-methyl-pyridin-2-yl)-methanol were place in a microwave vial. 6 mL of acetonitrile, 2 mL of toluene and 6 mL of a saturated aqueous solution of sodium carbonate were added. The vial was sealed and irradiated in a Personal Chemistry® Optimizer to 145° C. for 30 main. The resulting mixture was distributed between dichloromethane and a saturated aqueous solution of sodium bicarbonate. The aqueous layer was extracted twice with dichloromethane and the combined organic phases were dried over sodium sulfate and evaporated. The resulting residue was purified by flash chromatography on silica gel using a gradient of ethyl acetate in hexanes to afford a yellow oil. MS: m/z 553.0 (M+H+).
