Abstract

NEW MATERIAL:A compound of formula I (R1 is H, methyl; R2 is 1-4C alkyl; R3 is H, 1-4C alkyl) and its salt. EXAMPLE:9-Fluoro-3-methyl-10-( 3-methyl-1-piperazinyl )-7-oxo-2, 3-dihydro-7H-pyrido [1,2,3-d,e][1,4]benzoxazine-6-carboxylic acid. USE:Antibacterial: it shows a wide range of antibacterial action against gram- positive and-negative bacteria. PREPARATION:The reaction of a compound of formula II with a piperazine derivative of formula III is carried out in the absence of or presence of a solvent such as pyridine or alcohol at room temperature to 200 deg.C, preferably 100-180 deg.C to give the compound of formula I .
