Reaction Steps
A mixture of 2,4,6-trichloro-phenol (157.6 g, 0.8 mol), malonic acid (52 g, 0.5 mol), and POCl3 (98 mL, 1.05 mol) is heated at reflux for 4 hours. The reaction mixture is cooled slightly and poured into a mixture of ice, water, and ether with stirring. The solid is collected by filtration and dried in vacuo to give malonic acid bis(2,4,6-trichloro-phenyl)ester.
