Title: Manufacture of naphthioindoxyls
IPC: C07D333/74
Filed: 1923-06-07
Abstract: Naphthioindoxyls and their nuclear halogen derivatives are prepared by dissolving the corresponding thionaphthisatins in an alkali, converting the resulting thionaphthol-glyoxylic acid by means of a monohalogenacetic acid into the thioglycol-glyoxylic acid, eliminating carbon monoxide, and finally condensing the thioglycolcarboxylic acid to the naphthioindoxyl.  The thionaphthisatins are described in Specifications 186,859 and 214,864.  In an example 1 : 2-thionaphthisatin is dissolved in caustic soda, condensed with monochloracetic acid, and acidified to precipitate naphthalene-1-thioglycol-2-glyoxylic acid which is then treated with sulphuric acid of 90-94 per cent strength to eliminate carbon monoxide and to form the 1-thioglycol-2-carboxylic acid; the latter is then heated with acetic anhydride and the resulting acetyl-1 : 2-naphthioindoxyl hydrolyzed by means of alkali: the ring closure may also be effected by means of alkalies.  The following naphthioindoxyls may be similarly made from the corresponding naphthioisatins:- 4-chlor-1 : 2-naphthioindoxyl, 2 : 1-naphthioindoxyl, 5-chlor-, 5-brom-, and 8-chlor-2 : 1-naphthioindoxyl, 1-chlor- and 1-brom-2 : 3-naphthioindoxyl.
