Procedure

A solution of ethyl 3-[(5-methyl-4H-1,2,4-triazol-3-yl)amino]cyclobutanecarboxylate (7.85 g), ethyl 2-[(2′-cyano-3-fluorobiphenyl-4-yl)methyl]-3-oxohexanoate (23.15 g) and 1,8-diazabicyclo[5.4.0]undec-7-ene (2.62 mL) in N,N-diethylaniline (70 mL) was stirred at 180° C. for 20 hr. The reaction mixture was diluted with ethyl acetate, and the mixture was washed with 1 N 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 chromatography [eluent: hexane/ethyl acetate=85/15→65/35 (volume ratio)] to give the title compound as a pale-yellow amorphous compound (3.91 g, 21%).
