Procedure

A solution of 4-ethoxy-1,1,1-trifluoro-3-buten-2-one (4.21 g, 22.5 mmol), EtOH (42 mL), acetoacetamide (2.28 g, 22.5 mmol), and sodium ethoxide (21 weight % in EtOH, 8.41 mL, 22.5 mmol) was heated to 75° C. After 12 hours, the mixture was cooled to room temperature over 30 minutes, stirred for 4 hours, then cooled to <5° C. After 10 minutes, the white slurry was filtered, washing with cold EtOH (5 mL). The white solid was dried in a vacuum oven at 60° C. to provide the title compound (4.39 g, 19.3 mmol, 86% yield).
