- W2019989887 abstract "Treatment of methyl N-(4-chloro-5H-1,2,3-dithiazole-5-ylidene)anthranilate 1 with TiCl 4 (1.5 equiv.) in CH 2 Cl 2 at r.t., followed by addition of arylamines gave quinazolin-4-ones 2 bearing an aryl group at position 3 inmoderate yields. Similarly 4-hydroxy-4-phenylquinazolines 6 bearing an aryl group at position 3 were prepared in good to moderate yields from 2-[N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)(benzophenones, 5, TiCl 4 , and arylamines under the same conditions. The 1 H NMR spectra of 6 in CDCl 3 indicate that the compounds exist as an equilibrium mixture of 6 and the corresponding ring-opened compound, N-(2-benzoylaryl)-2-cyano-amidines 7. However, it is envisaged that compounds 6 exist as a single compound in a solid state in view of IR spectra showing no peak corresponding to a carbonyl absorption." @default.
