실험 절차

In a 100 mL round bottom flask, was added 0.4 g 1-Cyclohexylmethyl-4-(3,4-dichloro-phenyl)-5-pyridin-4-yl-pyrazolidin-3-one and 20 mL THF, stirred at 0° C. under nitrogen. 1.32 mL 1 M LHMDS in THF was added drop wise. After stirred at 0° C. for 30 min. 0.11 mL iodomethane was added drop wise. The resulted mixture was stirred from 0° C. to rt for 2 hour, quenched with 50 mL sat. NH4Cl, extracted with dichloromethane 3×25 mL. The organic phase was dried over anhydrous Na2SO4. After purification by flash chromatography, obtained the title compound 0.4 g as light solid. MS (ES+): 418 (M+H)+.
