Abstract
1 : 3-Diacetyl indazolone is prepared by refluxing indazolone and acetic anhydride. According to the literature, 1 : 2-diacetyl indazolone is obtained. 1 : 3-Diacetyl-4 : 6-dimethyl-5-azaindazolone is similarly prepared. 2 : 3-Dibenzoyl indazolone is prepared by adding benzoyl chloride to indazolone in pyridine and boiling. According to the literature, the 1 : 2-derivative is obtained. On boiling 1 : 3-diacetyl indazolone with water, 2-acetyl indazolone (1-acetyl indazolone according to the literature) is obtained and this is converted into 1-acetyl indazolone by melting at 220 DEG C. for 30 minutes. 2-Propionyl indazolone is prepared by refluxing indazolone and propionyl chloride in benzene. 2-(N-Pyridinium acetyl indazolone) - chloride is obtained by heating 2-chloroacetyl indazolone (see below) and pyridine. 2-Acetyl-4 : 6-dimethyl-5-azaindazolone is prepared by refluxing 4 : 5-dimethyl-5-azaindazolone in benzene with acetyl chloride. 2 - Benzoyl - 1 - acetyl indazolone is prepared by heating o-(beta-benzoyl hydrazino)-benzoic acid in acetic anhydride. Di-(2-carbonyl indazolonyl)-methane is prepared by heating malonyl chloride and indazolone in benzene. 2-Chloroacetyl indazolone is obtained by refluxing chloroacetyl chloride and indazolone in benzene, and 21-chloroquinolyl-41-carbonyl-2-indazolone is obtained similarly from 2-chloroquinoline-4-carboxylic acid chloride. 1 : 3 - Diacetyl - 7 - octadecenyl succinyl amino indazolone is prepared by boiling 7-octadecenyl succinyl amino indazolone with acetic anhydride. 1 : 3-Diacetyl-5-octadecenyl succinyl amino indazolone, and 1 : 3-diacetyl-5-stearoyl amino indazolone are similarly prepared. 1-Acetyl-7-octadecenyl succinyl amino indazolone and 1-acetyl-5-octadecenyl succinyl amino indazolone are prepared by treating the corresponding 1 : 3 - diacetyl compounds with aqueous caustic soda, leaving to stand overnight, filtering and neutralizing the filtrate with aqueous acetic acid. 2-Propionyl-6-octadecenyl-succinyl-amino indazolone is prepared by refluxing 6-octadecenyl-succinyl-amino indazolone with propionyl chloride in benzene. 1-Stearoyl-4-stearoylamino indazolone is prepared by refluxing 4-amino indazolone with stearoyl chloride in pyridine. Specification 685,061 also is referred to.
