実験手順

5-methyl-3-pyridineamine (191 mg), cesium carbonate (1.10 g), Pd2(dba)3 (186 mg), and Xantphos (235 mg) were added to a 1,4-dioxane (14 ml) solution containing tert-butyl cis-2-(6-chloro-5-cyano-3-fluoropyridin-2-ylamino)cyclohexylcarbamate (500 mg), followed by stirring at 100° C. for 2 hours in a nitrogen atmosphere. The reaction mixture was cooled to room temperature, and water and ethyl acetate were added. Insoluble matter was removed by filtration, the filter cake was washed with water and ethyl acetate, the organic layer was collected, washed with saturated saline, and dried over anhydrous magnesium sulfate, and the solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=10:0 to 1:4), diisopropylether was added, solid matter was collected by filtration, and a light yellow solid of tert-butyl cis-2-(6-(5-methylpyridin-3-ylamino)-5-cyano-3-fluoropyridin-2-ylamino)cyclohexylcarbamate (523 mg) was thus obtained.
