Abstract
Imidazonaphthothiazole derivatives III-VI were prepared by treatment of I w ith phencyl bromide, chloroacetic acid, diethyl oxalate and 2,3-dichloroqui noxaline respectively. The reaction of I with ethyl acrylate, ethyl acetoac etate and diethyl malonate gave the corresponding naphthothiazolopyrimidine derivatives VIII-XI.
