The Application of Some Alkyl Esters of Alkoxy Derivatives of N-Benzyl- N-phenyl-β-alanine in the Synthesis of 3-Amino-5-nitro[2,1]benzisothiazole-Based Dyes

This paper is concerned with the application of alkoxy derivatives of some alkyl esters of N-benzyl-N-phenyl-β-alanine in the synthesis of heterocyclic azo dyes derived from 3-amino-5-nitro [2,1] benzisothiazole. The structure of the alkoxy intermediates was confirmed by IR and 1H-NMR. The dyes were...

Description
Summary:This paper is concerned with the application of alkoxy derivatives of some alkyl esters of N-benzyl-N-phenyl-β-alanine in the synthesis of heterocyclic azo dyes derived from 3-amino-5-nitro [2,1] benzisothiazole. The structure of the alkoxy intermediates was confirmed by IR and 1H-NMR. The dyes were evaluated on polyester-fibre fabric with respect to their basic fastness properties. IR, 1H-NMR, and visible spectra of the dyes were also examined.
