3-Aminostyrene → (E)-5-(3-aminostyryl)-N2-(3-fluorophenyl)-N4-propylpyrimidine-2,4-diamine

Participants

Reaction Steps

To a solution of 3-vinylaniline (19 μL), N2-(3-fluorophenyl)-5-iodo-N4-propylpyrimidine-2,4-diamine (F2, 51 mg) and palladium(II) acetate (3 mg) in acetonitrile (1.5 mL), triethylamine (68 μL) was added at room temperature, and the mixture was stirred at the same temperature for 1 hour, and then stirred at 80° C. for 14 hours. The reaction mixture was cooled to room temperature, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 50% hexane in ethyl acetate) to obtain (E)-5-(3-aminostyryl)-N2-(3-fluorophenyl)-N4-propylpyrimidine-2,4-diamine (F11, 14 mg).
