Reaction Steps

50 mg (0.16 mmol) of 6-({2-[(7-chloro[1,2,4]triazolo[1,5-c]pyrimidin-5-yl)amino]ethyl}amino)-nicotinonitrile (Example 54A), 29.5 mg (0.16 mmol) of [4-(trifluoromethyl)phenyl]boronic acid and 18 mg (0.016 mmol) of tetrakis(triphenylphosphine)palladium(0) are introduced into a mixture of 3.3 ml of dioxane and 1.1 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 6.5 mg (10% of theory) of the product as a solid.
