Reaction Steps

Ethyl 2-[(trans-4-{6-[(2′-cyanobiphenyl-4-yl)methyl]-5-oxo-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl}cyclohexyl)oxy]butanoate (0.20 g) was dissolved in tetrahydrofuran (2 mL), methylmagnesium bromide (1.0 mL, 1.0 M tetrahydrofuran solution) was added dropwise at 0° C., and the mixture was stirred at room temperature for 1 hr. Methylmagnesium bromide (1.0 mL, 1.0 M tetrahydrofuran solution) was added, and the mixture was stirred at room temperature for 2 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 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 (0.12 g, 65%).
