To a solution of 529 mg of 4-[6-(4-benzyloxy-2-fluoro-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carbonyl]-3-phenyl-piperazine-1-carboxylic acid tert-butyl ester in 15 ml of dry THF 6 ml of borane-dimethylsulfide complex (1 M in DCM) was added slowly at r.t., and the reaction was heated to reflux for 30 min. The reaction was quenched by the addition of 3.75 ml of methanol, and the solvents were evaporated. The residue was purified by preparative HPLC (C18 column, acetonitrile/water gradient) yielding 266 mg (51%) of the title compound.
