실험 절차

A solution of 4-{4-[6-chloro-2-oxo-5-(trifluoromethyl)-2,3-dihydro-1H-benzimidazol-1-yl]-1-piperidinyl}tetrahydro-2H-pyran-4-carbonitrile (D65, 1160 mg, 0.37 mmol) in tetrahydrofuran (5 ml) was treated with methylmagnesium bromide (3M in diethyl ether, 1.0 ml, 3.0 mmol). After 2 h at room temperature the solution was partitioned between aqueous Rochelle salt solution and dichloromethane, and the organic layer was dried (MgSO4) and evaporated The residue was chromatographed on silica gel eluting with methanol-dichloromethane mixtures to afford the title compound, which was isolated as the hydrochloride salt triturated from diethyl ether (110 mg). MH+=418 and 420,
