Abstract
261,133. Ransford, A. J., (Cassella & Co., Ges., L.). Sept. 2, 1925. 2: 1-Benzoxazolone-5-arsinic acids are prepared by reducing 5-nitrobenzoxazolone or a derivative thereof and diazotizing the resulting amino compound in the presence of an arsenite. The products possess therapeutic properties. Examples are given of the production of 2 : 1-benzoxazolone- 5-arsinic acid from 5-nitro-benzoxazolone. 3-methyl-2:1-benzoxazolone-5-arsinic acid from 3-methyl-5-nitrobenzoxazolone, and 3-chlor-2:1- benzoxazolone-5-arsinic acid from 3-chlor-5-nitrobenzoxazolone. Specification 240,969 is referred to. 5-Nitrobenzoxazlone and its derivatives are obtained by the action of phosgene on 1-hydroxy- 2-amino-4-nitrobenzene and its derivatives. The preparation of 5-nitrobenzoxazolone from 4-nitro- 2-aminophenol, of 3-methyl-5-nitrobenzoxazolone from 5-nitro-3-amino-2-hydroxy-1-methylbenzene, and of 3-chlor-5-nitrobenzoxazolone from 5.nitro- 3-amino-2-hydroxy-1-chlorbenzene, is described. Monoazo dyes. - The 5-aminobenzoxazolones which result from the reduction of the 5-nitrobenzoxazolones may be diazotised and coupled with resorcinol or R-salt. Both 5-amino- and 3-methyl- 5-amino-benzoxazolones give yellow-red solutions with resorcinol and red-violet solutions with R- salt, whilst 3-chlor-5-aminobenzoxazolone gives an orange solution with resorcinol and a bluishred solution with R-salt.
