Palladium-catalyzed functionalization at the 2-position of various 5- and 7
-azaindoles was performed by Suzuki, Heck, and Stille reactions. The 2-subs
tituted azaindoles were obtained with 5% Pd(OAc)(2), LiCl, and KOAc in DMF
at 110 degrees C with moderate to high yields. (C) 2000 Elsevier Science Lt
