Carbon Dioxide → 2-Chloro-4,6-dimethoxy-1,3,5-triazine

Participants

Reaction Steps

To 45 g. of methanol and 5 g. of water were added 16.8 g. (0.2 mole) of sodium bicarbonate and 18.5 g. (0.1 mole) of cyanuric chloride. Carbon dioxide was liberated at a moderate rate as the temperature rose to 35°C. The mixture was refluxed for 30 minutes after gas evolution had nearly ceased. It was then cooled, diluted with water, and filtered. The crystalline product was washed with water until chloride free and was dried in a vacuum desiccator. The crude product weighed 13 g. (74% yield), m.p. 74°-76°C. Recrystallization from heptane gave m.p. 75°-76°C.
