Reaktionsschritte
4-(2-Hydroxy-ethoxy)-benzoic acid methyl ester (400 mg, 2.04 mmol) is combined with a mixture of 1 N NaOH (3 mL) and MeOH (3 mL) and the mixture is stirred at 80° C. for 1 h. The solvents are evaporated and the resulting residue is dissolved in a small amount of water and acidified with 1 N HCl. The crystals are collected, washed with water, and dried to provide 154 mg (42%) of the titled compound. NMR (DMSO-d6): δ 12.64 (br, 1H), 7.90 (d, 2H, J=8.2 Hz), 7.03 (d, 2H, J=8.2 Hz), 4.93 (br, 1H), 4.07 (t, 2H, J=4.9 Hz), 3.75 (m, 2H).
