Versuchsvorschrift

A mixture of 0.722 g 4-chloro-2-diisopropylaminomethyleneamino-5-iodopyrimidine, 3.5 mL triethylamine, 0.025 g copper iodide, 0.037 g dichlorobis(triphenyl)phosphine palladium II and 0.289 g 1-chloro-4-ethynylbenzene was stirred under nitrogen at room temperature for 18 hours. The dark brown mixture was evaporated in vacuo at a bath temperature of 30–35° C. The beige residue was partitioned between dichloromethane and water. The organic phase was washed twice with water, dried over sodium sulfate, filtered and evaporated to yield 1.0 g of a caramel colored film. The residue was dissolved in 1:1 dichloromethane/hexanes and purified by column chromatography on silica gel, eluting successively with 1:1 dichloromethane/hexanes, dichloromethane and ethyl acetate. The product was recovered from the latter two eluates by evaporation to yield 0.7 g of 4-chloro-5-(4-chlorophenylethynyl)-2-diisopropylaminomethyleneaminopyrimidine.
