実験手順

The reaction of ethyl 3-hydroxybenzoate and allyl bromide in 2-butanone in the presence of potassium carbonate was performed as described in Example 2 to give 3-Allyloxy-benzoic acid as white powder. 1H-NMR (400 MHz, d6-DMSO): 12.97 (s, —CO2H); 7.47 (d-like, 1 arom. H); 7.40 (m, 2 arom. H); 7.18 (m, 1 arom. H); 5.99 (m, —CH═CH2); 5.37, 5.23 (2 d-like, CH═CH2); 4.03 (d-like, CH2—CH_CH2). 13C-NMR (100 MHz, d6-DMSO): 167.08 (C═O); 158.12; 133.44; 132.27; 129.67; 121.66; 119.47; 117.47; 114.78; 68.27.
