Procedure

A mixture of ethyl 3-(4H-1,2,4-triazol-3-ylamino)cyclobutanecarboxylate (4.0 g), ethyl 2-[(2′-cyano-3-fluorobiphenyl-4-yl)methyl]-3-oxohexanoate (12 g) and N,N-diethylaniline (15 mL) was stirred at 180° C. for 48 hr and then at room temperature for 38 hr. The reaction mixture was added to 1 M hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was washed with 1 M hydrochloric acid and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (4.0 g, 41%).
