To a solution of N2-(3-fluorophenyl)-5-iodo-N4-propylpyrimidine-2,4-diamine (F2, 100 mg), bis(triphenylphosphine)palladium(II) dichloride (19 mg) and copper(I) iodide (10 mg) in N,N-dimethylformamide (2.7 mL), triethylamine (188 μL) and tert-butyl ((1S*,3R*)-3-ethynylcyclohexyl)carbamate (M3, 90 mg) were added at room temperature, and the mixture was stirred at the same temperature for 1 hour and 45 minutes. To the reaction mixture, water and ethyl acetate were added. The organic layer was separated, washed successively with saturated ammonium chloride and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 94 to 60% hexane in ethyl acetate) to obtain tert-butyl ((1S*,3R*)-3-((2-((3-fluorophenyl)amino)-4-(propylamino)pyrimidin-5-yl)ethynyl)cyclohexyl)carbamate (M4, 130 mg) as yellow solid.
