Process for producing arylsulfamates

Abstract

A process for producing an N-(heterocyclo-aminocarbonyl)-arylsulfamate of the general formula I ##STR1## wherein R.sub.1 is hydrogen, methoxy or C.sub.1 -C.sub.3 -alkyl, R.sub.2 is hydrogen, fluorine, chlorine, bromine, nitro, CF.sub.3, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkoxycarbonyl, R.sub.3 is hydrogen, fluorine, chlorine, bromine, methyl or C.sub.1 -C.sub.4 -alkoxy, R.sub.4 is hydrogen, fluorine, chlorine, bromine, nitro, cyano, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkoxycarbonyl, R.sub.5 is hydrogen, fluorine, chlorine, bromine, nitro or CF.sub.3, R.sub.6 is hydrogen, fluorine, chlorine, bromine, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, X is C.sub.1 -C.sub.2 -alkyl, C.sub.1 -C.sub.3 -alkoxy, C.sub.1 -C.sub.2 -alkylthio, methoxymethyl, methoxyethyl, CF.sub.3 or chlorine, Y is C.sub.1 -C.sub.2 -alkyl, C.sub.1 -C.sub.3 -alkoxy, C.sub.1 -C.sub.2 -alkylthio, methoxymethyl or methoxyethyl, and Z is the methine group or nitrogen, which process comprises adding, in an inert organic solvent, chlorosulfonylisocyanate of the formula III Cl--SO.sub.2 --N.dbd.C.dbd.O (III) to an aminoheterocyclic compound of the formula II ##STR2## wherein R.sub.1, X, Y and Z have the meanings defined under the formula I; and subsequently reacting this mixture, optionally with the addition of an agent binding hydrogen chloride, with a phenol of the formula IV ##STR3## wherein R.sub.2 and R.sub.3 have the meanings given under the formula I.
