実験手順

To a suspension of 1.24 g of 6-(4-methoxymethoxy-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid in 15 ml of DCM were added 2.1 ml of Hünig's base, 1.03 g of BEP and 0.87 g of 1-Benzyl-2,2,5,5-tetramethyl-piperazine. The reaction was stirred at r.t. for 3 h. For workup it was diluted with water and DCM and the layers were separated. The organic layer was washed with water twice, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by flash chromatography (silica, heptane/EtOAc gradient) to obtain 1.54 g (81%) of the title compound.
