Thiophosgene → 2,6-Dichloro-3-isothiocyanatopyridine

Participants

Reaction Steps

A slurry of sodium carbonate (15.2 g, 144 mmol), 2,6-dichloropyridin-3-amine (9.00 g, 55.2 mmol), and thiophosgene (5.50 mL, 71.8 mmol) in 100 mL anhydrous DCM was allowed to stir in a sealed vessel for 2 days. The reaction mixture was filtered through a glass frit, rinsing with DCM. The filtrate was concentrated in vacuo to give 2,6-dichloro-3-isothiocyanatopyridine as a peach-colored solid.
