Abstract

Procedure for the preparation of new ureas of the formula ** (see formula) ** In which R1 means a lower alpha-halogenoalkyl radical, R2 and r3 stand independently from each other, and each hydrogen or a lower alkyl radical, R4 means a lower alkyl radical optionally substituted by cyano or alkoxy, a cycloalkyl radical, an alkoxy radical, an alkenyl radical, alkenyl or alkynyl halogen, X means oxygen or sulfur, characterized in that an amine of formula ii ** (see formula) ** In which R1, r2 and x have the meanings indicated under formula i, Is transformed either with an ester of a carbonic halogen acid or with phosgene, in the presence of an acid-binding agent, into a carbamic acid derivative and this is reacted with an amine of the formula iii: ** (see formula) ** In which R3 and r4 have the meanings indicated under formula i.
