Abstract

Procedure for the preparation of phenyl substituted N-alkylcarbamates, of the general formula I ** (See formula) ** in which R1 and R2 are identical or different and each represent a hydrogen atom or a lower alkyl group, R represents a halogen atom, an aldehyde group or a grouping of the formula ** (See formula) ** in ortho or meta position with respect to the carbamoyloxy group, in which X and X are identical or different and each represent oxygen or sulfur, and R3 and R4 are identical or different and each represent an alkyl, alkenyl or alkynyl group or, together with any residue R, can form a 5-membered saturated or unsaturated heterocycle, containing X1 and X2 as heteroatoms), characterized in that it comprises reacting a compound of the general formula II ** (See formula) ** in which R is as defined above, in the presence of a base, with a compound of the general formula III (see formula) (Machine-translation by Google Translate, not legally binding)
