4-(Trifluoromethyl)aniline → HCID 18953981, compound

Participants

Reaction Steps

A mixture of 10.14 g (65 mmol) of ethyl 3-cyclopropyl-3-oxopropanoate and 10.47 g (65 mmol) of 4-aminobenzotrifluoride in 100 ml of dry toluene was refluxed for 8 hours using a Dean-Stark condenser to remove the ethanol formed during the reaction. The reaction mixture was cooled and petroleum ether (b.p. 40°-60° C.) was added to obtain 16.44 g (93%) of 3-cyclopropyl-3-oxo-N-[4-(trifluoromethyl)phenyl]-propanamide as a white crystalline solid, melting at 131°-2° C.
