Versuchsvorschrift

To a solution of 4′-[(4-{4-[1-(1-formylcyclobutyl)ethoxy]cyclohexyl}-5-oxo-7-propyl-4,5-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-6-yl)methyl]biphenyl-2-carbonitrile (10.35 g) in tetrahydrofuran (50 mL) was added 1 M methylmagnesium bromide-tetrahydrofuran solution (27 mL), and the mixture was stirred at room temperature for 15 hr. 1 N Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. To a solution of the residue in acetonitrile (200 mL) was added 1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one (8.48 g), and the mixture was stirred at room temperature for 2 hr. Saturated aqueous sodium hydrogen carbonate solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed 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=80/20→60/40 (volume ratio)] to give the title compound as a colorless amorphous compound (8.32 g, 79%).
