Terephthalic acid (2.5 g, 0.015 mol) was titrated with a 40% aqueous solution of tetraethylammonium hydroxide (11.3 mL). The solvent was evaporated to obtain a hard residue which was dissolved in methanol. The methanol was evaporated to obtain 5.8 g, 92% yield of salt. FIG. 43, FIG. 43A and FIG. 43B show a 1H NMR spectrum and FIG. 44 shows a 13C NMR spectrum of the salt in DMSO-d6.
