実験手順

A mixture of 2.46 g 4-chloro-2-diisopropylaminomethyleneamino-5-iodopyrimidine, 7.5 mL triethylamine, 0.064 g copper iodide, 0.12 g dichlorobis(triphenyl)phosphine palladium II and 0.9 mL phenylacetylene was stirred under nitrogen at room temperature for two days. The dark brown mixture was evaporated in vacuo at a bath temperature of 30–35° C. The residue was partitioned between dichloromethane and water. The organic phase was washed thrice with water, dried over sodium sulfate, filtered and evaporated to yield 3.37 g of a dark brown oil. The residue was dissolved in hexanes and purified by column chromatography on silica gel, eluting successively with hexanes, 1:1 dichloromethane/hexanes and dichloromethane. The product was obtained from the latter eluant to yield after evaporation, 1.69 (74%) g of 4-chloro-2-diisopropylaminomethyleneamino-5-phenylethynylpyrimidine.
