Definitions
- These compounds are useful as anti-inflammatory agents.
- a compound of l structure I is successivel treated with a base such as con y R2 R sodium hydride and an acid chloride in a solvent such 1 as dimethylformamide to form a monoacyl derivative so; of formula II.
- Diacyl derivatives such as III are formed In by heating I with an acid anhydride.
- the cyclic derivatives of formula IV are formed as a ll result of an internal diacylation reaction. This is 0 achieved by the treatment of I with a base such as so- I :0 R1 dium hydride followed by the addition of either phosgene (COCl or an alkylor aralkylchloroformate so. "(5 .59 1.) IV in a solvent such as dimethylformamide.
- the starting material I is prepared as described in cowherein R and R are hydrogen, alkyl, aryl, aralkyl, pending application Ser. No. 163,076 filed July 15, alkoxy, halogen, cyano, nitro, trifluoromethyl, and the 1971, now abandoned.
- R, R and R alkyl and The compounds of this invention are useful as antialkoxy have 1 to 7 carbon atoms such as methyl, inflammatory agents for mammals, i.e. cats, dogs, monethyl, propyl, isopropyl and the like, aryl has 6 to 8 keys and the like.
- aryl has 6 to 8 keys and the like.
- aryl when they are adminiscarbon atoms such as phenyl or tolyl, and aralkyl is tered orally or intraperitoneally to laboratory animals aryl as defined substituted by an alkyl group as defined.
- rats at a dose of 25-200 mg/kg, they reduce the swelling in the paw which has been previously induced
- an irritant such as carrageenin. following examples are included:
- R and R are hydrogen, alkyl of 1 to 7 carbon atoms, aryl of 6 to 8 carbon atoms, aralkyl in which alkyl is as defined and substituted by an alkyl group as defined, alkoxy of l to 7 carbon atoms, halogen, cyano, nitro and trifluoromethyl.
