Abstract

1 : 2 : 4-Oxadiazoles of the formula <FORM:0817286/IV (b)/1> wherein R is an alkyl, aryl or substituted aryl group, are prepared by reacting cyano-acetic acid chloride with amidoximes of the formula R-SO2-CH2-C(NH2)=NOH The amidoximes are prepared by treating nitriles of the formula R.SO2.CH2.CN with NH2OH, and the nitriles are obtained by the reaction of chloro-aceto-nitrile with the sodium or magnesium salts of sulphinic acids (R.SO2H). Examples are given of the above reactions wherein R is p-tolyl, b -naphthyl, p-nitrophenyl, 3-nitro-4-methyl-phenyl and n-butyl. 1 - (Delta - sulphobutyl) - 6 - aminotetrahydroquinoline is prepared by reducing the azo dye from diazotized sulphanilic acid and 1-(delta-sulpho - butyl) - tetrahydroquinoline potassium salt by means of hydrogen under pressure and a nickel catalyst. 1-(Delta-sulphobutyl)-tetrahydroquinoline is obtained by heating tetrahydroquinoline with butane sultone on the water bath. By adding potassium hydroxide it is obtained in the form of its potassium salt. Specifications 540,760, [Group XX], 645,043 and U.S.A. Specifications 2,566,259 and 2,707,681 are referred to.ALSO:An azo dye is formed from diazotized sulphanilic acid and 1-(delta-sulphobutyl)-tetrahydroquinoline potassium salt. Specifications 540,760, 645,043, [both in Group XX], and U.S.A. Specifications 2,566,259 and 2,707,681 are referred to.
