Conditions

Temperature: 180 °C

Procedure

A mixture of 5-(trans-4-{6-[(2′-cyanobiphenyl-4-yl)methyl]-5-oxo-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl}cyclohexyl)-1,3-oxazole-4-carboxylic acid (0.94 g), copper(II) oxide (0.005 g) and quinoline (5 mL) was stirred at 180° C. for 16 hr. 1 N Hydrochloric acid and ethyl acetate were added to the reaction mixture, and the insoluble material was filtered off through celite. The obtained organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound as a colorless solid (0.65 g, 75%).
