Versuchsvorschrift

To a mixture of 6-(4-hydroxy-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (215 mg), DIPEA (313 μL) and 1-benzyl-4-methyl-piperidin-4-ylamine (175 mg) in dichloroethane (7 mL), which was being stirred at 40° C., was added BEP (200 mg). The mixture was stirred at 40° C. for 60 min, then at r.t. overnight. Water was added and the mixture was extracted with dichloromethane. To the dichloromethane phase 30% sodium methoxide in methanol (0.4 mL) was added and stirred for 30 min. The mixture was filtered and the filtrate was washed with water, dried over magnesium sulfate and concentrated. The residue was chromatographed over silica (dichloromethane/methanol gradient) to give 1420 g (43%) of the title compound.
