To a 1 liter, 3 necked round bottomed flask equipped with a paddle stirrer, condenser, thermometer and heating source, were added 135 g (0.80 mole) of 2,6-bis(hydroxymethyl)-4-methylphenol, followed by 9 g (0.10 moles) of oxalic acid and 200 g (1.61 moles) of 4-methylcatechol. To this mixture were added 400 g of water. The reaction mixture was stirred and heated to 70° C. Solution occurred when the temperature reached approximately 60° C. Then, the reaction mixture was heated to reflux and held at reflux for 4 hours. After 1 hour at reflux, the product began to separate.
