Versuchsvorschrift
Diethanolamine (4.4 g) was dissolved in water (5 mL), and this solution was added to the ether solution of α-methylacetoacetic acid while cooling with ice. A solution of silver nitrate (6.8 g) dissolved in water (8 mL) was then added dropwise. The white precipitate that precipitated was filtered off, washed with ice water and then isopropanol, and then dried, yielding silver α-methylacetoacetate as a white precipitate (yield 4.78 g).
