Abstract
NEW MATERIAL:A pyridone derivative of formula I [one of R1 is lower alkyl group, and the other two are H; R2 is H, lower lakyl, or piperidino lower alkyl group; R3 is lower alkyl; (amino-substituted) phenyl or formula IV (n is 1W3; R1' is the same as R1)], and its nontoxic salt.
EXAMPLE: 1,4-Dimethyl-6-methylamino-2-pyridone.
USE: A nalgesics and anti-inflammatory agents, administered clinically in a dose of 100W1000mg, preferably 150W600mg/day/adult usually two or three times.
PROCESS: A compound of formula II (X is halogen), e.g. 6-chloro-1,4-dimethyl-2- pyridone, is reacted with an equimolar or excess of a compound, e.g. methylamine, of formula III in an organic solvent, preferably under refluxing, to give the objective compound of formula I. A base, e.g. an alkali carbonate, may be added to the system.
