Colorless to light yellow liquid.
2-Chloro-4-methylpyridine is used as a reagent in the synthesis of the mGLUR5 modulators imidazolyl-ethynyl-pyridines as potential antipsychotics. It is also used in the preparation of trifluoromethyl(pyrimidinyl)azetidinecarboxamides as potent, orally bioavailable TGR5 agonists.
2-Chloro-4-methylpyridine (2-Chloro-4-picoline) reacts with 3,5-bis(trifluoromethyl)phenylboronic acid to form 2-(3,5-bis(trifluoromethyl)phenyl)-4-methylpyridine by palladium-catalyzed cross-coupling reaction.
