According to instructions in the literature (Baraznenok, I. L., Nenajdenko, V. G., Balenkova, E. S. Eur. J. Org. Chem. 1999, 937–941), 1.2 g (7.18 mmol) of (E)-4-(dimethylamino)-1,1,1-trifluoro-3-buten-2-one is reacted with 2.03 g (7.18 mmol) of trifluoroacetic acid anhydride and 1.30 ml (14.36 mmol) of aniline in 72 ml of 1,2-dichloroethane, then in 36 ml of xylene.
