  摘要：

  Ethyl 4-[1-(dimethylamino)-3-ethoxy-3-oxoprop-1-en-2-yl]-2-[(dimethylamino)methylideneamino]thiazole-5-carboxylate (2), prepared from ethyl 2-amino-4-(2-ethoxy-2-oxoethyl)thiazole-5-carboxylate (1) according to a known procedure, was transformed with aromatic amines 3a-d into 5-aryl substituted 2-aminothiazolo[5,4-c]pyridine-7-carboxylates 5a-d, while treatment of 2 with monosubstituted hydrazines 6a-h produced 5-N-amino substituted thiazolo[5,4-c]pyridine-7-carboxylates 8a-h.
