Participants

Reaction Steps

To a solution of (4S)-4-hydroxy-1-(1-methyl-1H-pyrazol-3-yl)pyrrolidin-2-one (97 mg) in THF (3.0 mL) was added a sodium hydride 60% dispersion in mineral oil (24 mg) under ice-cooling, and the mixture was stirred under ice-cooling for 10 min. Iodomethane (50 μL) was added to the reaction mixture under ice-cooling, and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (30 mg).
