General description

2-Chloro-5-iodopyridine is a halo-substituted pyridine.

Application

2-Chloro-5-iodopyridine may be used as a reagent in the multi-step synthesis of (±)-epibatidine.
It may be used in the synthesis of:
  • 2-Chloro-5-phenylpyridine via Suzuki coupling reaction with phenylboronic acid dimethyl ester.
  • Exo-5- and exo-6- (6′-chloro-3′-pyridyl)-2-azabicyclo[2.2.1]heptanes via Heck coupling reaction with N-protected 2-azabicyclo[2.2.1]hept-5-enes.
  • Substituted diaryliodonium salts.
  • 3-Exo-5′-(2′-Chloropyridinyl)-8-(ethoxycarbonyl)-8-azabicyclo[3.2.1]octane.
