Procedure
The reaction of isobutyl bromide and ethyl 3-hydroxybenzoate in the presence of potassium carbonate was performed as described for Compound 24 to give 3-isobutoxy-benzoic acid as white powder. 1H-NMR (400 MHz, d6-DMSO): 12.94 (s, COOH); 7.48 (m, 1 arom. H); 7.40 (m, 2 arom. H); 7.12 (m, 1 arom. H); 3.76 (d, J=6.4, (CH3)2CHCH2O); 2.00 (m, (CH3)2CHCH2O); 0.96 (d, J=6.4, (CH3)2CHCH2O). 13C-NMR (100 MHz, d6-DMSO): 167.11 (—C═O); 158.73; 132.12; 129.68; 121.42; 119.35; 114.46; 73.46; 27.66; 18.98 (2 C).
