반응 단계
A slurry of mono-methyl terephthalic acid (32-1, Aldrich) (0.25 g, 1.4 mmol) and 19-2a (0.5 g, 1.4 mmol) in acetonitrile (7 mL) was treated with N-methyl morpholine (0.31 mL, 2.8 mmol) and BOP reagent (0.62 g, 1.4 mmol) for 24 h. The solution was diluted with EtOAc, washed with H2O, 10% KHSO4, saturated NaHCO3 and brine. The organic layer was dried over MgSO4, filtered and evaporated to give a tan solid. Column chromatography (40% EtOAc/Hexanes) gave 32-2 as a white solid.
