Reaction Steps
A solution of γ-butyrolactone (1.92 mL, 2.15 g, 25.0 mmol), 60% suspension of sodium hydride in mineral oil (300 mg, 7.50 mmol) and 3-acetylpyridine (551 μL, 606 mg, 5.00 mmol) in dimethylsulfoxyde (4 mL) and tetrahydrofuran (36 mL) was stirred overnight at 25° C. Ethanol (4 mL) was added to destroy excess sodium hydride and the reaction mixture was adsorbed on silica gel (10 g). Flash chromatography on silica gel (75 g), eluting with DCM/MeOH/NH4OH (96/4/1), gave 1.14 g of a yellow oil containing compound 3-A (0.62 g, 60%).
