Reaction Steps
A mixture of 2-aminopyrazine (230 mg, 2.42 mmol), sodium tert-butoxide (232 mg, 2.42 mmol) and bis(tri-t-butylphosphine)palladium (0) (51 mg, 0.1 mmol) in toluene (2 mL) was degassed under a stream of nitrogen over 10 min. 4,6-Dichloropyrimidine (300 mg, 2.01 mmol) was added to the mixture and the reaction was heated at 80° C. for 2 h. After cooling, the solution was passed through a PS-SH cartridge and the solvent removed in vacuo. The residue was triturated with dichloromethane and the resulting solid was collected and dried by vacuum filtration to give crude 6-chloro-N-(pyrazin-2-yl)pyrimidin-4-amine (333 mg) which was used without further purification.
