Abstract

Pyrazolones of the general formula <FORM:0833596/IV (b)/1> wherein R is an alkyl group of from 8 to 18 carbon atoms, D is -CO-, -CH2CO- or -OCH2CO-, and Y is hydrogen, ammonium or an alkali metal, are prepared by treating 3-amino-1-phenyl-5-pyrazolone with an acyl chloride of the formula <FORM:0833596/IV (b)/2> reducing the nitro compound formed to the corresponding amino compound and condensing this with an a -sulpho-fatty acid of the formula R.CH(SO3H)-COOH. Examples are given of the reaction of 1-phenyl-3-amino-5-pyrazolone with 4-nitrobenzoyl chloride or p-nitrophenoxy acetyl chloride to give 3-p-nitrobenzamido-1-phenyl - 5 - pyrazolone or 3 - p - nitrophenoxy-acetamido - 1 - phenyl - 5 - pyrazolone respectively, and of the reduction of these with anhydrous ferrous sulphate in ammonia to give the corresponding amino compounds. Examples are also given of the reaction of a -sulphostearic acid monosodium salt with 3-(p-aminobenzamido) - 1 - phenyl - 5 - pyrazolone, 3 - (31-aminobenazamido) - 1 - phenyl - 5 - pyrazolone, or 3 - (p - aminophenylacetamido) - 1 - phenyl5 - pyrazolone to give respectively 1 - phenyl 3 - (p - a - sulphostearamido - benzamido) - 5 - pyrazolone, 1 - phenyl - 3 - (31 - a - sulphostearamido - benzamido) - 5 - pyrazolone or 1-phenyl - 3 - (p - a - sulphostearamido - phenyl-acetamido) - 5 - pyrazolone. Alternatively, 1-phenyl - 3 - (p - a - sulphostearamido - benzamido)-5-pyrazolone is made by reacting 3-amino - 1 - phenyl - 5 - pyrazolone with p-(a -sulphostearamido) benzoic acid. It is stated that instead of a -sulphostearaic acid, the a -sulpho-derivative of capric, lauric, myristic or palmitic acids may be used in any of the above reactions.
