  Effects of Various Bases on Acid-Catalyzed Amination of 2-Chloro-5-ethylpyrimidine: Synthesis of PPARpan Agonist GW693085

  摘要：

  A unique buffering effect of various bases, i-Pr2NEt and CaCO3 in particular, was observed for the acid-catalyzed chloro displacement of 2-chloro-5-ethylpyrimidine with a 2-methyl-2-phenylpropanamine. The use of the carefully chosen bases was essential for the progression of the chloro displacement as well as the stability of the product in the presence of HCl formed. Research work leading to an efficient synthesis of PPARpan agonist GW693085 is described, featuring highly selective sequential N- and O-alkylations.
