Dimethylcarbamoyl Chloride → HCID 18998869, compound

Participants

Reaction Steps

In acetonitrile were suspended 0.80 g of 3-hydroxy-4-phenoxy-1,2,5-thiadiazole and 0.46 g of potassium carbonate and after adding 0.36 g of dimethylcarbamoyl chloride to the suspension, the mixture was refluxed for 12 hours. After allowing to cool, the reaction mixture was poured in water and extracted with ether. The ether layer was washed twice each time with a diluted aqueous solution of sodium hydroxide, water, and then a saturated aqueous sodium chloride solution. The ether layer thus washed was dried with anhydrous magnesium sulfate, concentrated, and thereafter purified by silica gel column chromatography to provide 0.85 g of 3-phenoxy-1,2,5-thiadiazol-4-yl N,N-dimethylcarbamate.
