반응 단계

tert-Butyl 3-carbamothioylpyrrolidine-1-carboxylate (5 g, 21.71 mmol), 2-chloromalonaldehyde (3.70 g, 34.7 mmol) and magnesium carbonate (1.830 g, 21.71 mmol) were combined in dioxane (100 ml). The mixture was heated to 60° C. for 3 hours, stirred overnight at room temperature and then filtered through a pad of diatomaceous earth, rinsing with dichloromethane. The filtrate was concentrated in vacuo and then purified by normal phase chromatography to provide the title compound.
