| titleOfInvention | Process for preparing carbamates and intermediates therein |
| abstract | The invention provides a process for the preparation of N-benzoylcarbamates of general formula <CHEM> wherein R<1> represents a hydrogen atom, a halogen atom, a C1-4 alkyl group, a C1-4 alkoxy group or a trifluoromethyl group, R<2> represents a halogen atom, a C1-4 alkyl group, a C1-4 alkoxy group or a trifluoromethyl group, R<3> represents a hydrogen atom, a halogen atom, a methyl group or a trifluoromethyl group, and R represents a C1-8 alkyl group optionally substituted by one or more halogen atoms or a phenyl group optionally substituted by one or more substituents selected from halogen atoms and methyl groups, characterised by reacting an alkali metal salt of a benzamide of general formula <CHEM> wherein R<1>, R<2> and R<3> are as defined above, with a carbonate of formula RO-CO-OR (III) wherein R is as defined above, in the presence of an inert solvent, and neutralising the resulting alkali metal salt of the compound of formula I; and (intermediate) alkali metal salts of the compounds of formula I. |
