实验步骤: A solution of 5.0 g (24.4 mmol) of 2-(2-hydroxy-1-methylethyl)-1H-isoindole-1,3(2H)-dione (Y. Becker, A. Eisenstadt, J. K. Stille, J. Org. Chem., 1980, 45, 2145) and triphenylphosphine (7.00 g, 27.0 mmol) in 40 mL of dry tetrahydrofuran was stirred at 20° C. for 1 h. To the solution was added 2-ethylphenol (3.90 g, 32.0 mmol) and diethyl azodicarboxylate (5.0 mL, 32.0 mmol) and the solution was stirred an additional 40 h. The reaction mixture was concentrated in vacuo and the residue was diluted in diethyl ether and washed with water and brine. The organic layer was concentrated in vacuo and the crude product was purified by flash silica chromatography using 5% ethyl acetate/hexanes solution as eluent to give 3.0 g (40%) of 2-[2-(2-ethylphenoxy)-1-methylethyl]-1H-isoindole-1,3(2H)-dione as a colorless oil: 1H NMR (CDCl3) δ 0.96 (t, 3H), 1.60 (d, 3H), 2.40 (m, 2H), 4.18 (dd, 1H), 4.48 (t, 1H), 4.84 (m, 1H), 6.80 (m, 1H), 6.90 (m, 1H), 7.10 (m, 2H), 7.70 (m, 2H), 7.84 (m, 2H). The reaction mixture was concentrated in vacuo the residue was diluted in diethyl ether washed with water and brine The organic layer was concentrated in vacuo the crude product was purified by flash silica chromatography
