Patent ID: 7317105

Claim:
A process for preparing 4-haloalkylnicotinamides of the formula (I) where R 1 is (C 1 -C 4 )-haloalkyl, which comprises subjecting one or more 3-((C 1 -C 4 -haloalkyl-3-oxo-1-alkenylamino)nitriles of the formula (II), (III) and/or (IV) R 1 —C(O)—CH═CH—NH—CH═CH—CN (II) R 1 —C(O)—CH═CH—NH—CH(ZR 2 )—CH 2 —CN (III) R 1 —C(O)—CH═CH—NH—CH(Hal)—CH 2 —CN (IV) where R 1 is as defined above; R 2 is the same or different and is (C 1 -C 6 )-alkyl and Z is the same or different and is O, S or NR 1 , to a ring-closing reaction and simultaneous hydrolysis in the presence of a strong acid having a pK a value of below 0.5.
