Abstract

The invention comprises pyrazolones of the formula in which R is alkyl, amino, acylamino or substituted phenylureido, X is hydrogen, nitro, amino, acylamino, substituted phenylureido or sulpho, and also cyanoacetyl benzenes of the formula in which X is hydrogen or acylamino and Y is hydrogen, alkyl or cyanoacetyl. The pyrazolones of the above formula are made by (i) condensing 4-hydrazino-diphenyl sulphone or a nitro derivative thereof with ethyl acetoacetate or methyl stearoyl-acetate, or with ethyl b -imino-b -ethoxy-propionate followed by hydrolysis (Examples 1, 2, 4, 6 and 12); (ii) by oxidizing a corresponding sulphide (Example 7); (iii) by acylation of an aminophenylsulphonylphenylpyrazolone (Examples 3 and 8-12); (iv) by reduction of a nitrophenylsulphonylphenylpyrazolone to form the amine (Examples 5, 10 and 12); (v) by hydrolysis of a chlorosulphonylphenylsulphonylphenylpyrazolone (Example 12); and (vi) by reacting aminophenylsulphonylphenylpyrazolones with 4-chlorosulphonyl phenyl isocyanate and then with 3-amino-5-stearoylamino-benzoic acid to form a substituted phenylureido derivative (Examples 13 and 14). The cyanoacetyldiphenylsulphones of the above formula are made by brominating the corresponding acetyldiphenylsulphones and reacting the product with an alkali-metal cyanide (Examples 15, 17 and 18), or by acylating an amino-cyanoacetyldiphenylsulphone (Example 16). 4-Hydrazino-diphenylsulphone and its 3-nitro derivative are made by reacting hydrazine with 4-chloro-diphenylsulphone and 3-nitro-4-chlorodiphenylsulphone (from 3-nitro-4-chlorobenzene-sulphonyl chloride and benzene in the presence of AlCl3), respectively (Examples 1 and 4). 2 – Acetylamino – 4 – acetyl – 41 – methyl – diphenyl-sulphone and 2-myristylamino-4:41-diacetyl-diphenylsulphone are made by acylating respectively 2 – amino – 4 – acetyl – 41 – methyl – diphenylsulphone and 2 – amino – 4:41 – diacetyl-diphenylsulphone prepared by reducing the corresponding 2-nitro-derivatives made by condensing 3-nitro-4-chloro-acetophenone with sodium p-toluene sulphinate dihydrate and sodium 4-acetylbenzene sulphinate respectively (Examples 15 and 17). 4-Acetyldiphenylsulphone is made by oxidizing the corresponding sulphide with hydrogen peroxide (Example 18). Sodium 4-acetyl-benzenesulphinate is made by heating sodium sulphite with 4-acetyl-benzene-sulphonyl chloride prepared by reacting diazotized p-aminoacetophenone with sulphur dioxide and cuprous chloride (Example 17).
