Abstract

1393470 Substituted aminophenoxy salicylic acid compounds BAYER AG 2 July 1973 [1 July 1972] 31471/73 Heading C2C The invention relates to substituted aminophenoxy salicylic acid compounds of the general formula in which R represents a hydrogen atom, a C 7 to C 10 aralkyl radical or a one-linkage C 6 to C 10 aromatic radical, R<SP>1</SP> represents a hydrogen atom, an aliphatic C 2 to C 5 acyl radical, an aromatic C 7 to C 10 acyl radical, a carboxylate radical COOR<SP>11</SP> where R<SP>11</SP> represents a C 1 to C 4 alkyl radical, or a C 7 to C 10 aralkyl radical, X and Y which may be the same or different represent a hydrogen atom, chloride, bromide or a C 1 to C 4 alkyl radical. The compounds may be produced from the corresponding nitrophenoxy salicylic acids by reducing nitro compounds in the presence of known catalysts to amino compounds by conventional methods, acylating and esterifying the amino compounds with anhydrides, carboxylic acid chlorides and with chlorocarbonic acid esters. Amino and acetamino phenoxy and halogenated phenoxy salicylic acid and phenyl esters thereof are described and claimed. The preparation of polybenz-1, 3-oxazin-(2, 4)-diones is also described.
