実験手順

To a mixture of potassium carbonate (78 mg, 0.56 mmol, Fisher), tetrabutylammonium hydrogen sulfate (10. mg, 0.029 mmol, Aldrich) and N,N-dimethylformamide (2.00 mL, Acros) was added 2-(1-nitro-ethyl)-6-(trans-4-trifluoromethyl-cyclohexyloxy)-naphthalene (0.159 g, 0.433 mmol). The mixture was stirred and methyl acrylate (50 μL, 0.56 mmol, Aldrich) was added. The mixture was stirred at room temperature. After 2 h, ethyl acetate was added and the solution was washed with saturated ammonium chloride, then saturated sodium chloride. The organics were dried over Na2SO4, filtered, concentrated. The residue was taken up in DCM, and silica gel was added. The solvent was removed and the residue was purified by silica gel chromatography (0-25% EtOAc in hexanes). Isolated was 98 mg (50%) of product (Rf=0.19 in 7:1 hexanes/ethyl acetate).
