Abstract

Disubstituted carbamic acid esters of aromatic hydroxy compounds containing a tertiary nitrogen atom in aliphatic or heterocyclic combination are prepared by (1) interaction of dialkyl-, arylalkyl-or diaryl-carbamic acid halides with the alkali salts of aromatic hydroxy compounds containing a tertiary nitrogen atom in aliphatic or heterocyclic combination, or (2) treating the carbamic acid esters of aromatic hydroxy compounds containing a tertiary nitrogen atom in aliphatic or heterocyclic combination with dialkyl-, arylalkyl- or diaryl-amines or piperidine. The products possess similar properties to physostigmine. Examples are given of the preparation of (1) the methylphenyl- and diphenyl-carbamic acid esters of m-dimethyl-aminophenol from methylphenyl- and diphenyl-carbamic acid chlorides respectively and m-dimethylaminophenol; in the same way, the dimethylcarbamic acid esters of o-oxybenzyldiethylamine, 8-hydroxyquinoline and m-dimethylaminophenol are obtained; (3) the pentamethylene-carbamic acid ester of m-dimethylaminophenol from tetramethyl-m-m-diaminophenylcarbonic acid ester and piperidine. Specification 342,237 is referred to. o-Oxybenzyldiethylamine is prepared from phenol, formaldehyde and diethylamine.
