3-(Trifluoromethyl)aniline → Ethyl 3-oxo-3-{[3-(trifluoromethyl)phenyl]amino}propanoate

Participants

Reaction Steps

To an ice-cooled solution of 3-(trifluoromethyl)aniline (64.5 g, 0.40 mol) and triethylamine (60 ml) in acetone (700 ml) was added dropwise, ethyl 3-chloro-3-oxopropanoate (63.6 g, 0.42 mol) in acetone (50 ml). After the addition was complete (approx. 30 minutes), stirring was continued at RT overnight. The solvents were removed and water (1200 ml) was added. The resulting precipitate was filtered off, thoroughly washed twice with water and then dried to afford ethyl 3-oxo-3-{[3-(trifluoromethyl)phenyl]amino}propanoate as a yellow powder (109 g, 99%).
