Conditions

Temperature: 150 °C

Procedure

A microwave vial was charged with trifluoro-methanesulfonic acid 3-{2-[4-(2-pyrrolidin-1-yl-ethoxy)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-5-yl}-phenyl ester (50 mg, 0.09 mmol), benzeneboronic acid (15 mg, 0.12 mmol), tetrakis(triphenylphosphine)palladium (10 mg, 0.009 mmol), potassium phosphate (0.5M in water, 0.36 ml, 0.18 mmol) and N,N′-dimethylacetamide (1 ml). The reaction was heated to 150° C. for 10 minutes under microwave irradiation. The mixture was then filtered through a plug of silica, washed with methanol and concentrated in vacuo. The product was purified by preparatory LCMS to yield the desired product. RT: 2.96 min, MI: 476.22, Method: 2
