実験手順
To a solution of pyrrolidine-1,3-dicarboxylic acid-1-tert-butyl ester (3.40 g) in N,N-dimethylformamide (34 ml) were added potassium carbonate (4.37 g) and 3-bromo-3,3-difluoropropene (1.93 ml), and the mixture was stirred at 60° C. for 6 hours. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=5/1) to give the titled compound (3.73 g).
