A stirred mixture of molten sodium metal (24.15 g, 1.05 mol) in toluene is treated with ethanol (55.2 g, 1.2 mol) over a 1 hr period at 100° C.-110° C., heated at reflux temperatures for 0.5 hr, cooled to 30° C., treated with diethyl oxalate (160.6 g, 1.1 mol) over a 10 min period at 30° C.-45° C., treated with ethyl ethoxyacetate (132 g, 98%, 0.98 mol) over an 0.5 hr period at 45° C.-50° C., heated at 55° C.-60° C. for 1.5 hr and poured into 328 g of 14% HCl with cooling. The resultant mixture is separated. The title product is obtained in the organic phase as a 40.9% solution, identified by HRGC analysis, total yield is 204.2 g (90% yield).
