Toluene → Methyl 4-chloro-6-(chloromethyl)pyridine-2-carboxylate

Participants

Reaction Steps

To a solution of methyl 4-chloro-6-(hydroxymethyl)-2-pyridinecarboxylate (166 mg, Ref: Kittika et al., Tetrahedron, 44 (10), 2821, (1988)) in dry dichloromethane (3 ml) was added thionyl chloride (66 μl). The solution was stirred for 40 minutes. LC/MS indication reaction completion. Solvent was removed u.r.p. (under reduced pressure) to give a white solid. Toluene (˜2 ml) added then removed u.r.p. The residue was dried in vacuo to give a white solid. (175 mg, 97%). LC/MS [MH+]=220/222, Rt=2.51 min. Title compound obtained as the free base.
