Procedure

The reaction was carried out in a manner similar to Reference Example 12 b) except for using 14.6 g (46.9 mmol) of 3-benzyloxy-6-trifluoromethyl-2-nitrotoluene, 13.7 g (93.8 mmol) of diethyl oxalate, 7.90 g (93.8 mmol) of potassium ethoxide and 300 ml of diethyl ether. Ethyl (3-benzyloxy-6-trifluoromethyl-2-nitrophenyl)pyruvate was thus obtained in the yield of 10.9 g (56.9%).
