THE SYNTHESIS OF SOME COMPLEX QUINAZOLINE DERIVATIVES CONTAINING ONE OR TWO QUINAZOLINE RINGS AND CARRYING AMINO, ACYLAMINO, ESTER AND/OR CARBAMATE FUNCTIONAL GROUPS IN THEIR SIDE CHAINS

The scope of the Bischler synthesis has been extented to the synthesis of complex quinazoline derivatives 3b-3d, 5a-5f, 6a, 6b, 7 and 8.Reductive cleavage of the C-N bond of all 4-(N-monosubstituted aminomethyl)quinazolines tested took place on treatment with ethanol in the presence of acids or bases.
