Abstract

NEW MATERIAL:A compound of formulaI[R is lower alkyl; R1 is lower alkyl, -B-R2 (B is lower alkylene; R2 is carboxyl, lower alkoxycarbonyl, lower alkoxy, di-lower-alkylamino); A is carbonyl, methylene, Y is O, S; X is H, lower alkyl] or its salt.
EXAMPLE: 5-Methoxy-3-( 5H-[1]benzopyrano[2,3-b]pyridin-7-yl )-2-pentanone.
USE: It has antirheumatic, analgesic, antipyretic and brain metabolism-improving activities and is used as a medicine.
PREPARATION: The reaction of compound of formula II with another compound of R1-Z (Z is acid residue of active ester) is conducted in an inert solvent to give the compound of formulaI.
