A mixture of 50 g (60 mmol) of Merrifield resin (polCH2Cl where pol=1-2% crosslinked polystyrene, 200-400 mesh beads), 2,2′-dihydroxy-1,1′-binaphthalene-3,3′-dicarboxylic acid (33.7 g), potassium carbonate (12.4 g) and DMF (dimethlyformamide) (350 ml) was heated at 90° C. with stirring for 8 hrs. The color of the resin changed from white to green-yellow. The mixture was diluted with water, filtered, washed with H2O, DMF, and acetone, and then thoroughly dried in the air to give the desired product. IR (KBr, cm−1): 1712 (vs), 1676 (vs).
