Title: Amino-2-acyl-phenol ethers
IPC: C07C233/12
Filed: 1959-07-13
Abstract: The invention comprises compounds of the general formula: <FORM:0863702/IV (b)/1> in which R is a hydrogen atom, a straight or branched alkyl C1-6, a hydroxyalkyl C1-6 or alkoxy C1-6 alkyl radical and R1 is a hydrogen atom, a straight or branched alkyl C1-6, acyl or hydroxy-acyl radical, a hydroxyalkyl C1-6 alkoxy C1-6 alkyl or alkenyl C1-6 radical and R2 is a straight or branched alkyl C1-11 radical or a phenyl residue and R3 is a hydrogen or halogen atom or an alkoxy radical and R5 is a hydrogen or halogen atom or a straight or branched alkyl C1-6 radical and R6 is a halogen atom or a hydroxyl radical or a straight or branched alkoxy C1-6 radical, an aliphatic acyloxy C1-6 radical or a halogenomethyl radical and N can be 0, 1 or 2 and the group -NRR1 is situated at the 4 or 5 position of the aromatic nucleus shown in the formula; and acid addition salts of basic compounds of the formula I; and the preparation thereof by reacting a compound of the formula:  <FORM:0863702/IV (b)/2> with a compound of the formula: Y-CH2-CHR5-(O-CH2-CHR5)n-R6 in which Y is a halo gen atom or an aromatic sulphonic acid radical or, where R6 is a hydroxyl group, by reacting a compound of the formula II with a compound of the formula:  <FORM:0863702/IV (b)/3> or, where R6 is an alkoxy or an acyloxy radical, by reacting a compound of the formula: <FORM:0863702/IV (b)/4> with Me-R (Me is an alkali metal atom) or, where R5 is a halogen atom and R6 is a halogenomethyl radical and n is zero, by halogenating a compound of the formula:  <FORM:0863702/IV (b)/5> or, where R and R1 are hydrogen atoms, by reducing the corresponding nitro compound or, where NRR1 represents a secondary or tertiary amine group, by alkylating or hydroxyalkylating the corresponding primary amino compound or, where R1 represents an acyl group, by acylating the corresponding primary or secondary amino compound or, where R6 is an acyloxy radical, by acylating the corresponding hydroxy compound and, if desired, converting basic products of any of these processes into their acid addition salts. The invention also includes pharmaceutical compositions containing the products.  The products have antipyretic, antiphlogistic and analgesic activity.  2-Acetyl-4-acetamido phenyl allyl ether is prepared by reacting 2-acetyl-4-acetamidophenol and allyl chloride in the presence of alkali.  2-Acetyl-4-nitrophenyl b -methoxyethyl ether is prepared by reacting 2-acetyl-4-nitro-phenol and p-toluene sulphonic acid b -methoxyethyl ether.ALSO:Pharmaceutical compositions comprise compounds of the formula <FORM:0863702/VI/1> in which R is a hydrogen atom, a straight or branched alkyl C1-6 radical, a hydroxyalkyl C1-6 or alkoxy C1-6 alkyl radical and R1 is a hydrogen atom, a straight or branched alkyl C1-6, acyl or hydroxy-acyl radical, a hydroxy-alkyl C1-6, alkoxy C1-6 alkyl or alkenyl C1-6 radical and R2 is a straight or branched alkyl C1-11 radical or a phenyl radical and R3 is a hydrogen or halogen atom or an alkoxy radical and R5 is a hydrogen or halogen atom or a straight or branched alkyl C1-6 radical and R6 is a halogen atom or a hydroxyl radical or a straight or branched alkoxy C1-6 radical, an aliphatic acyloxy C1-6 radical or a halogenomethyl radical and n can be 0, 1 or 2, and the group-NRR1 is situated at the 4- or 5-position of the aromatic nucleus shown in the formula, or acid addition salts (e.g. hydrochlorides, sulphates, phosphates, acetates, lactates or citrates) of the basic compounds of the formula I, with a pharmaceutical carrier.
