Diethanolamine (0.33 g) was dissolved in water (5 mL), and to this was added an ether solution (10 mL) containing isobutyrylacetic acid (0.43 g). Next, the mixture was stirred at 15° C. while an aqueous solution (5 mL) containing silver nitrate (0.51 g) was added dropwise, and this further was stirred for 15 minutes. The white precipitate that settled was filtered off to obtain silver isobutyrylacetate (yield 0.37 g). FIG. 1 shows the infrared absorption spectrum (IR) of the silver isobutyrylacetate that was obtained. IR:1709 cm−1, 1505 cm−1.
