実験手順

N-(4-{[tert-Butyl(dimethyl)silyl]oxy}cyclohexyl)-1H-1,2,3-triazol-5-amine (5.55 g) and a solution of ethyl 2-[(2′-cyanobiphenyl-4-yl)methyl]-3-oxohexanoate (13.07 g) and 1,8-diazabicyclo[5.4.0]undec-7-ene (2.85 g) in N,N-diethylaniline (30 mL) were stirred at 185° C. for 15 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=90/10→80/20 (volume ratio)] to give the title compound as a brown amorphous compound (1.58 g, 15%).
