Procedure

In 20 g of methanol was dissolved 3.9 g of phenylglyoxylic acid (Aldrich), and 0.9 g of sodium hydroxide (Wako Pure Chemical Industries, Ltd.) was added thereto little by little (generation of heat caused by neutralization was observed). After stirring for 1 hour, 10.4 g of 1 mol/L aqueous silver nitrate solution (Wako Pure Chemical Industries, Ltd.) was added thereto. Then a precipitated gray solid was collected by filtration, washed with methanol, and dried, so that 4.4 g of silver phenylglyoxylate (gray solid) was obtained.
