참여 물질

반응 단계

A solution of benzyl 2,5-dihydro-1H-pyrrole-1-carboxylate (0.626 mL, 0.00349 mol), methyl 3-bromo-benzoate (300 mg, 0.001 mol), palladium(II) diacetate (14 mg, 0.000063 mol), potassium acetate (356 mg, 0.00363 mol), and tetra-N-butylammonium bromide (4.50×10−2 mg, 0.00140 mol) in N,N-dimethylformamide (5 mL, 0.06 mol) was stirred under nitrogen at 40° C. for 4 days. The reaction mixture was diluted with AcOEt and water. The organic layer was separated and the aqueous layer was extracted with AcOEt. The combined organic layer was washed with brine, dried with MgSO4, and concentrated to afford the crude product. The crude product was purified by flash chromatography, eluting with 30% AcOEt in hexanes.
