In this paper we report the preparation of a series of 4(3H) quinazolinones substituted in the 2 position by a linear perfluoroalkyl-chain with RF as Cn F2n+1 (n=1,3,5,7).These compounds are obtained in two steps, action of F-acid chlorides on 2-aminobenzonitrile which affords the corresponding F-amides followed by cyclization of this intermediate with alkaline hydrogen peroxide.We isolated a reaction intermediate in the cyclization of N-(2-cyanophenyl)F-octanamide.All compounds were identified by the usual spectroscopic methods (IR, NMR 1H, 19F, mass spectrometry).
