Procedure

Ethyl 2-methyl-4,4,4-trifluoroacetoacetate (10.2g, 51 mmoles), ammonium acetate (11.9, 150 mmoles), ethanol (20 g), and water (1 g) were combined in a 100 mL round-bottom flask. The mixture was heated for 6 hr. at 70° C. The mixture was then cooled to room temperature and poured into water (50 mL). The aqueous mixture was extracted with ethyl acetate (approximately 40 mL) and the layers were separated. The ethyl acetate layer was dried over anhydrous magnesium sulfate and evaporated to give an 88% yield of ethyl 3-amino-2-methyl-4,4,4-trifluorocrotonate.
