Conditions

Temperature: 150 °C

Procedure

60 mg (0.19 mmol) of 6-({2-[(7-chloro[1,2,4]triazolo[1,5-c]pyrimidin-5-yl)amino]ethyl}amino)nicotinonitrile (Example 54A), 35.6 mg (0.19 mmol) of (2,4-dichlorophenyl)boronic acid and 21.6 mg (0.019 mmol) of tetrakis(triphenylphosphine)palladium(0) are introduced into a mixture of 4 ml of dioxane and 1.3 ml of saturated aqueous sodium carbonate solution under argon. The mixture is degassed with argon and then heated in a microwave at 150° C. for 30 min. Cooling is followed by filtration through an Extrelut® cartridge. Purification by preparative HPLC results in 15.3 mg (19% of theory) of the product as a solid.
