実験手順

A solution of 0.5 M 9-borabicyclo[3.3.1]nonane in tetrahydrofuran (141.3 ml) was added to a solution of (S)-tert-butyl (1-(4-amino-6-bromo-5-(quinolin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)but-3-en-2-yl)carbamate (6.0 g) obtained in Reference Example 1 in tetrahydrofuran (42 ml) under a nitrogen atmosphere at room temperature, and stirred at room temperature for 2 hours. A 2 N sodium hydroxide aqueous solution (84.8 ml) was slowly added to the reaction mixture at room temperature, and degassed under reduced pressure. Under a nitrogen atmosphere, (tetrakistriphenylphosphine)palladium(0) (1.70 g) was added thereto, and the mixture was stirred at 66° C. for 12 hours. After the reaction mixture was cooled, the organic layer was separated and washed with a 20% ammonium chloride aqueous solution (60 ml). SH silica gel (6.0 g) was then added to the organic layer, and the result was stirred at 50° C. under a nitrogen atmosphere for 14 hours, and then filtered. SH silica gel (produced by Fuji Silysia Chemical Ltd.) (6.0 g) was added to the filtrate again, and the result was stirred under a nitrogen atmosphere at 50° C. for 14 hours, and then filtered. The solvent was distilled off from the filtrate under reduced pressure. The resulting residue was purified by silica gel column chromatography (developing solvent: ethyl acetate/methanol) to obtain the title compound (4.46 g) (yield: 88%) as a light-yellow solid.
