Reaction Steps
2-Hydroxy-5-sulfonicotinic acid (500 g, 2.28 mol) was dissolved in ethanol (2.5 L) with stirring and heated to 80° C. After 30 mins 0.5 L of solvent was distilled off, then replaced with fresh ethanol (0.5 L) and taken back to 80° C. After a further 60 mins 1.0 L of solvent was distilled off, then replaced with fresh ethanol (1.0 L) and taken back to 80° C. After a further 60 mins 1.0 L of solvent was distilled off, the reaction cooled to 22° C. and stirred for 16 hr.
