Reaction Steps
325 g of sodium hydride (80% solution in paraffin oil) were suspended in 2500 cc of diethyl carbonate and 500 cc of hexamethyl phosphoric acid triamide, 500 g of pinacolone (92%) were then slowly added dropwise at 45° to 50° C. and, on completion of the addition the reaction mixture was treated as described in 3 above. The yield was 91% of pivaloyl acetic acid ethyl ester.
