Reaction Steps

To a 2000 ml 3 neck round bottom equipped with an overhead stirrer, temperature probe, heating mantel was added 2,2′-dihydroxy-biphenyl (500 g, 2.68 mole, 1.0 eq), ethylene carbonate (520.2 g, 5.9 mole, 2.2 eq.), potassium iodide (5 g, 0.03 mole, 0.01 eq.), N,N-dimethyl formamide (DMF) (47 g, 50 ml) and heated to 150° C. The reaction was monitored by GC and after 4 hours the reaction was complete. The reaction was cooled to 40° C., added 1000 ml ethyl acetate and washed 3 times with 500 ml sodium chloride brine. The ethyl acetate was dried over MgSO4, filtered and concentrated in vacuo to recover a dark brown product (736 g, 99%).
