## Abstract A new approach to 2‐amino‐6‐(methoxycarbonyl)amino‐4‐(1,2,3,6‐tetrahydro‐1‐pyridyl)pyrimidine 1‐oxide (**3**) is described. Methyl [1‐ethoxy‐2‐(ethoxycarbonyl)‐ethylidene]carbamate (**5**) reacted with guanidine to the pyrimidinecarbamate **6**, which was successively transformed into m
4-Hydroxy-2,3,5,6-tetrafluorobenzoic acid/6-hydroxy-2-naphthoic acid copolymers (FHBA/HNA copolymer) with different copolymer compositions were prepared and the influence of FHBA residue on the thermal properties and structures of the copolymers were investigated. Introduction of FHBA decreased the
