Reaction Steps

To a solution of dimethylamino-{3-[3-(2-methoxy-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyrazolo[3,4-b]pyridin-5-yl]-phenyl}-acetic acid (56 mg, 0.11 mmol), dimethylamine (2 N in THF, 0.08 mL, 0.16 mmol), and diisopropylethylamine (21 mg, 0.16 mmol) in THF (1.5 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (61 mg, 0.16 mmol.). The resulting suspension was heated to 60° C. with stirring until all was dissolved. The solvent was evaporated and the residue was used in next step without purification. MS: m/z 560 (M+H+).
