Phosgene-free process for preparing carbamates from compounds containing amine groups |
| abstract |
A phosgene-free method for preparing a carbamate from a compound containing an amine group involves reacting the compound with an alkylating agent such as chloromethyl pivalate in the presence of carbon dioxide and cesium carbonate is disclosed. A reaction can take place under standard pressure and temperature conditions, in presence of a polar aprotic solvent such as dimethyl formamide and produces carbamates in a high yield with low by-product formation. |
