Abstract
Deprotection of 1 with KOH in toluene obtained terminal acetylene derivative 2,then the compound 3 was obtained by the reaction of 2 with 5-bromo-2-dodecylpyrimidine via Sonogashira cross coupling reaction.The TBS protecting group of 3 was easily deprotected by TBAF to give 4.Finally,the D-π-A type compound 5 was synthesized by the reaction of 4 and 2-(2-(2-methoxyethoxy) ethoxy) ethyl 4-methylbenzenesulfonate,and characterized by1H NMR and MALDI-TOF mass.
