Procedure

Trans-4-mercaptocyclohexanol (0.050 g), tris(dibenzylideneacetone)dipalladium(0) (0.008 g), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (0.010 g), and N,N-diisopropylethylamine (0.116 mL) were added to a solution of (40f) (0.150 g) prepared in Example 40(6) in 1,4-dioxane (1.71 mL), followed by stirring under nitrogen flow at 120° C. for 6 hr. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with saturated saline. The organic layer after the washing was dried over anhydrous sodium sulfate, and the solvent was distilled away. The residue was purified by neutral silica gel column chromatography (n-hexane/ethyl acetate) to obtain a crude product of 2-(trans-4-hydroxycyclohexylthio)-4-{3-methyl-4-(quinolin-3-yl)-1H-pyrrolo[2,3-b]pyridin-1-yl}benzonitrile. Subsequently, an aqueous sodium hydroxide solution (4 M, 0.851 mL) and a 30% hydrogen peroxide solution (0.193 mL) were added to a solution of this 2-(trans-4-hydroxycyclohexylthio)-4-{3-methyl-4-(quinolin-3-yl)-1H-pyrrolo[2,3-b]pyridin-1-yl}benzonitrile in DMSO (0.4 mL) and ethanol (1.6 mL) at room temperature, followed by stirring for 30 min. Water was added to the reaction solution, and the precipitate was collected by filtration, washed by sprinkling water and ether, and then dried under reduced pressure to obtain (67) (0.023 g, the second stage yield: 13%) as a white solid.
