Abstract

111 In two cases side reactions predominated over the cyclization. When ethylamine was used, methyl anthranilate was isolated in nearly 60% yield along with a small amount of the anticipated 3-ethyl-3, d-dihydro-4-keto-1, 2, 3-benzotriazine. This same phenomenon accompanied the formation of a bis-ketobenzotriazinylethylene from ethylenediamine. Evidently, in these reactions the intermediate I1 tautomerizes to an interrnediate such as ...
