反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To PPA in toluene at 100° C., was added 4-(2-methoxyphenoxy)butanoic acid and the mixture stirred overnight. The mixture was poured onto ice-water, and extracted with ether (3 times). The combined organic phase was washed with water and dried over anhydrous sodium sulfate. Evaporation of the organic phase afforded a light yellow oil in 10% yield: 1H NMR δ 7.33 (dd, 1H, J=4.4, 5.1 Hz), 7.03 (d, 2H, J=4.3 Hz), 4.31 (t, 2H, J=6.6 Hz), 3.90 (s, 3H), 2.90 (t, 2H, J=6.9 Hz), 2.22 (p, 2H, J=6.8 Hz). The mixture was poured onto ice-water extracted with ether (3 times) The combined organic phase was washed with water dried over anhydrous sodium sulfate Evaporation of the organic phase afforded a light yellow oil in 10% yield
