Abstract
NEW MATERIAL:3-Carbamoyl-pyrazolo[1,5-a]pyridine of formula I.
USE: An analgesic and anti-inflammatory agent without side effects, e.g. gastric disorder, with low toxicity.
PROCESS: 3-Cyano-pyrazolo[1,5-a]pyridine of formula II is hydrolyzed with preferably inorganic acid at 0W150°C for about 1W10hr to give the compound of formula I. Alternatively, 3-carboxy-pyrazolo[1,5-a]pyridine is converted into an acid halogenide, which is then reacted with ammonia to afford the compound of formula I.
