Abstract

1,182,202. Indazolones. FERRANIA S.p.A. 13 March, 1967 [23 March, 1966], No. 11747/67. Heading C2. [Also in Division G2] 5 - Phenylureido - indazolone is made by hydrolysis of 2 - tosyl - 5 - phenylureid - indazolone prepared by treatment with phenylisocyanate of 2-tosyl-5-amino-indazolone. The latter is made by reduction of 2-tosyl-5-nitroindazolone obtained by reaction of 5-nitro indazolone with p-toluenesulphochloride. 5 - [4<SP>1 </SP>- (3<SP>11</SP> - Stearoylamino - 5<SP>11</SP> - carboxy)- anilinosulphonyl] phenylureido - indazolone is made by hydrolysis of the corresponding 2-tosyl derivative prepared by refluxing 3-amino-5- stearoylamino-benzoic acid with the solution obtained by heating p-chlorosulphophenyl isocyanate and 2-tosyl-5-amino-indazolone in dioxane. 5 - Benzoylamino - indazolone is made by hydrolysis of 2 - tosyl - 5 - benzoylamino - indazolone prepared by reacting 2-tosyl-5-aminoindazolone with benzoyl chloride. 5-[3<SP>1</SP>-(3<SP>11</SP>- Stearoylamino - 5<SP>11</SP> - carboxy) - anilinosulphonyl]- benzoylamino-indazolone is made by hydrolysis of the corresponding 2-tosyl derivative obtained by refluxing 3-amino-5-stearoylaminobenzoic acid with a solution obtained by reacting mchlorosulpho-benzoyl chloride with 2-tosyl-5- amino-indazolone.
