Reaction Steps

A mixture of 4-{5-[2-amino-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]-pyrazol-1-yl}-benzonitrile (Ex. 1, 230 mg, 0.50 mmol) and 4-methyl-morpholine (300 mg, 30.0 mmol) in THF (3 mL) was treated with dihydro-furan-2,5-dione (250 mg, 2.50 mmol) and heated at 120° C. under microwave irradiation for 4 hrs and then thermally at 60° C. for four days. The crude reaction mixture was purified by flash chromatography eluting with a gradient of 0-10% MeOH in DCM. The fractions containing product were concentrated in vacuo affording the title compound as a colorless glass which solidified in a white solid by standing (182 mg).
