To a 50 ml 1 neck round bottom was added 2,6-diphenylphenol (10 g, 1 eq), ethylene carbonate (3.9 g, 1.1 eq), potassium iodide (0.07 g, 0.01 eq), dimethylformamide (1 g, 0.3 eq) and heated to 150 C. After 4 hours the reaction was cooled to 40 C, added 30 ml ethyl acetate and washed 2 times with 20 ml sodium chloride brine, 3 times with 20 ml DI water and again with 20 ml brine. The ethyl acetate was dried with (1 g) magnesium sulfate, filtered and concentrated invacuo to recover an off-white solid. Mp 77-78
