Procedure
A solution of 53.05 g (0.186 mol) of 2-(4-(N-salicyloyl)aminophenyl-)propionic acid and 300 ml of ethanol is treated with 7.59 g (0.190 mol) of NaOH dissolved in 22 ml of water. The reaction mixture is stirred for 30 min at 25° C. and for 30 min at 0° C. The resulting pale yellow solid is isolated by filtration to give 52.61 g of sodium 2-(4-(N-salicyloyl)aminophenyl)propionate. Properties. Solubility: 200 mg/ml clear solution, pH=6.85. Analysis C, 60.45; H, 5.45; N, 3.92; Na, 6.43. Melting point 236–238° C.
