Abstract
[N-[(3, 4-dihydro-2-methyl-4-oxo-6-quinazolinyl~ methy11-N-prop-2-yny1amino1benzoy11- ~-g1utam-ic acid (IC1 198583, 1) is described in which the glutamic acid residue has been replaced by other a-amino acids. Most of these analogues were prepared by coupling of tert- butyl-4-(prop-2-yny1amino) benzoate (37) with 6-(bromomethyl)-3, 4-dihydro-2-methyl-4- oxoquinazoline (34) followed by deprotection of the tert-butyl ester to the acid and azide- ...
