Participants

Reaction Steps

Concentrated Sulfuric acid (1.0 mL, 18.8 mmol) was added to tert-butyl 4-oxo-3-(2-oxo-1,2-dihydropyridin-3-yl)piperidine-1-carboxylate (350 mg, 1.20 mmol). The resulting thick solution was stirred at room temperature overnight. The reaction was heated at 60° C. until reaction complete by LCMS. The reaction was diluted with 90% Acetonitrile 10% Water and solid potassium carbonate was added cautiously to neutral pH (Effervescence), the slurry was filtered and the filtrate evaporated, the resulting residue was used without further purification.
