The synthesis of 2,4-disubstituted quinazolines by a palladium-catalyzed reaction of arylboronic acids with N-(2-cyanoaryl)benzamides has been developed with moderate to excellent yields. The method shows good functional group tolerance. In particular, ha

2,4-Dichloroquinolines and 2,4-dichloroquinazolines were synthesized from 2-ethynylanilines and anthranilonitriles, respectively, using diphosgene in acetonitrile and heating at 130 °C or 150 °C for 12 hours. This reaction was applied to the synthesis of 4,6-dichloropyrazolo[3,4-d]pyrimidine (dichloro-9H-isopurine). The postulated mechanism is also described. Georg Thieme Verlag Stuttgart.

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).
