Abstract

297,363. Kalle & Co. Akt.-Ges. Sept. 19, 1927, [Convention date]. Diazo compounds.-A diazo compound is obtained in the usual manner from 1-(5<1>-amino-2<1>- piperidyl - benzoylamino)-8-hydroxynaphthalene- 3 : 6-disulphonic acid, which is prepared by condensing 1-amino-8-oxynaphthalene - 3 : 6 - disulphonic acid with 5-nitro-2-chlorobenzoylchloride, causing the condensation product to react with piperidine, and reducing the nitro compound in the usual manner.
