実験手順

To a solution of 350 mg of [(R)-4-Benzyl-3-(2,2,2-trifluoro-ethyl)-piperazin-1-yl]-[6-(4-methoxymethoxy-phenyl)-3-methyl-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridin-4-yl]-methanone in 6 ml of dry THF 4.4 ml of borane-dimethylsulfide complex (1 M in DCM) was added slowly at r.t., and the reaction was heated to reflux for 6 h. The reaction was quenched by the addition of methanol, and the solvents were evaporated. The residue was purified by flash chromatography (silica, heptanes/ethyl acetate) yielding 217 mg (63%) of the title compound.
