Abstract
1,051,497. Naphthalene tetracarboxylic acid diimides. FARBENFABRIKEN BAYER A.B. Aug. 4, 1964 [Aug. 2, 1963], No. 31718/64. Heading C2C. Novel compounds of the Formula I wherein X represents a direct bond or a C 1-2 alkylene radical; A represents a direct bond or a C 1-6 alkylene radical; R and R 1 represent C 1-8 alkyl radicals or R and R 1 are joined to form an alkylene chain; Z represents a direct bond or an oxygen atom or a group of the formula -CH 2 - or -N(B)- where B represents a hydrogen atom or a C 1-8 alkyl radical; R 2 represents a hydrogen atom or a C 1-4 alkoxy radical, with the proviso that when A represents a direct bond, Z does not represent an oxygen atom or an -N(B)- group and salts thereof with physiologically acceptable, non-toxic, organic and inorganic acids are prepared by reacting naphthalene-(1,4,5,8)-tetracarboxylic acid or its dianhydride with an amine of the Formula II in the presence of a solvent or in a melt 4 - Butoxy - 5 - piperidinomethylaniline is prepared by etherification of 5-nitrosalicylic acid ethyl ester with butyl bromide and conversion of the ether into the acid amide with piperidine followed by reduction. 4-Piperidinomethylaniline is prepared by reacting p-nitrobenzoyl chloride with piperidine and reducing the product.
