Reaction Steps
9.39 g of potassium carbonate and 4.39 g of ethylene carbonate are added to 20 g of the product from Example A6 in 200 ml of anhydrous DMF. The reaction mixture is heated at 140° C. for 18 h. The salts which precipitate are filtered off and washed with toluene. The combined organic phase is freed of solvent in vac. and used directly for the further reaction.
