Abstract
NEW MATERIAL:The thiopyrano[4,5-b]pyridin-2-one derivative of formula I (R1 is H or lower alkyl; R2 is H, lower alkyl, hydroxy lower alkyl, phenyl lower alkyl which may have nitro, amino, etc. as substituent on the phenyl ring, or phenyl which may have substituent groups; l is 0, 1 or 2) and its salt.
EXAMPLE: 1-[ 2-( 2-Methoxyphenyl)ethyl ]-1,2,3,4,4a,5-hexahydro-7H-thiopyrano [4,5-b] pyridin-2-on-4a-yl-carboxylic acid methyl ester.
USE: It has antiphlogistic and blood platelet coagulation inhibiting activities, and is useful as an antiphlogistic agent and a preventive and remedy for thrombosis.
PROCESS: The compound of formula I is prepared by the cyclization reaction of the compound of formula II with the compound of formula R2-NH2 in a proper solvent (e.g. benzene).
