以相应的β-酮胺为原料，通过环缩合反应制备了含有甲基、苯基、2-噻基和2-呋喃基的2,6-二取代4-吡啶基非叶酸酯。钯催化的交叉偶联（Suzuki-Miyaura， Mizoroki-Heck和Sonogashira反应）导致了构建块，这些构建块是预期的推拉型溶剂化染料合成的直接前体。
2,6-Disubstituted 4-pyridyl nonaflates including methyl, phenyl, 2-thienyl and 2-furyl groups were prepared by cyclocondensation reactions of the appropriate β-ketoenamides. Palladium-catalyzed cross-couplings (Suzuki–Miyaura, Mizoroki–Heck and Sonogashira reactions) led to buildings blocks that are direct precursors for the envisioned synthesis of push–pull solvatochromic dyes.
