Procedure

0.625 mol Potassium tert.-butylate, 542 ml. diethyl oxalate and 95.7 g. 2-allyloxy-6-nitrotoluene are stirred for 3 hours at 60° C., then mixed with 1 N acetic acid and extracted with diethyl ether. The oxalic acid ester remaining behind in the ether residue is removed at an elevated temperature at water-pump pressure, 171 g. ethyl 2-allyloxy-6-nitrophenylpyruvate being obtained.
