Mode opératoire

The procedure of Example 1 was followed using diethyl oxalate (3.0 mL, 22 mmol), potassium trimethylsilanolate (3.85 g, 22 mmol), dry ether (70 mL), an ice bath to maintain room temperature initially, and a 1.5 h reaction time. Potassium ethyl oxalate (2.72 g, 79% yield) was isolated as a white solid: 1H NMR (D2O) δ 1.3 (t, J=7.2 Hz, CH3, 3H), 4.2 ppm (q, J=7.2 Hz, CH2, 2H). Anal. Calcd. for C4H5KO4 : C, 30.76; H, 3.23; K, 25.04. Found: C, 30.39; H, 3.29; K, 25.30.
