Participants

Reaction Steps

To a solution of 1.54 g of (4-benzyl-2,2,5,5-tetramethyl-piperazin-1-yl)-[6-(4-methoxy-methoxy-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridin-4-yl]-methanone in 9 ml of dry THF 20 ml of borane-dimethylsulfide complex (1 M in DCM) was added slowly at r.t., and the reaction was heated to reflux for 12 h. The reaction was quenched by the addition of 13 ml of methanol, and the solvents were evaporated. The residue was purified by flash chromatography (silica, heptanes/ethyl acetate) yielding 1.44 g (96%) of the title compound.
