실험 절차

In a vial containing 1-(1,1-dimethylethyl) 2-methyl (2S,5R)-5-(4-bromophenyl)-1,2-pyrrolidinedicarboxylate (D78, 100 mg, 0.26 mmol), sodium carbonate (138 mg, 1.30 mmol), 4,4,5,5-tetramethyl-2-[(E)-2-phenylethenyl]-1,3,2-dioxaborolane (90 mg, 0.39 mmol) and Pd(PPh3)4 (30 mg, 0.026 mmol) were added dioxane (2 ml) and water (1 ml). The mixture was stirred for 2 h at 80° C. After cooling, the mixture was extracted with ethyl acetate. The organic layer was filtered by phase separator tube and evaporated. The residue was purified by chromatography on silica gel using cyclohexane/ethyl acetate (1:0 to 9:1) to afford the title compound as a light yellow solid (90 mg, 85%). Rt (HPLC): 7.02 min; MS: (ES/+) m/z: 308 (MH-Boc) C25H29NO4 requires 407.
