| abstract | 1,223,890. Substituted ureidophenyl phenyl carbamates. BADISCHE ANILIN- & SODA FABRIK A.G. 30 May, 1968 [31 May, 1967], No. 25928/68. Heading C2C. [Also in Division A5] The invention relates to substituted ureidophenyl phenyl carbamates of the general formula in which R<SP>1</SP> denotes a phenyl radical which may be substituted by halogen, nitro, methoxy, carboxy, lower alkyl or lower haloalkyl, or a cycloaliphatic radical having 3 to 8 carbon atoms in the cycloaliphatic ring which may be substituted by halogen or alkyl and R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> and R<SP>5</SP> denote hydrogen, a phenyl radical, or a lower saturated or unsaturated aliphatic hydrocarbon radical which may be substituted by halogen, the term " lower alkyl " denoting an alkyl radical having 1 to 4 carbon atoms. The compounds may be prepared by treating a N - (m-hydroxyphenyl) - N<SP>1</SP> - substituted urea with a carbamyl halide R<SP>1</SP>R<SP>2</SP>NCOX wherein X is halogen. Compounds in which R<SP>2</SP> is hydrogen may be prepared by treating a N-(m-hydroxyphenyl)-N<SP>1</SP> substituted urea with an isocyanate R<SP>1</SP>NCO. The intermediate N-(m-hydroxyphenyl)-N<SP>1</SP> substituted ureas may be prepared by reacting a m-aminophenol with the appropriate carbamyl halides preferably chloride, in the presence of agents binding hydrogen halide, or with appropriate isocyanates. Compounds claimed per se are m-(methylureido) - phenyl N - m - methylphenyl - carbamate and m-(3,3-dimethylureido)-phenyl N-p-chlorophenyl carbamate. In an example, dimethyl carbamyl chloride is reacted with m-aminophenol to produce N-(m-hydroxyphenyl)-N<SP>1</SP>,N<SP>1</SP>-dimethylurea which is reacted with p-chlorophenyl isocyanate to produce m - (3,3 - dimethylureido) - phenyl N -p - chlorophenyl carbamate. |
