Abstract
NEW MATERIAL:A pyrazoquinoline of formula I: (ring A is pyrazolo ring at the 5-and 6-positions of the quinoline ring; R1 is hydroxy lower alkyl, lower alkenyl, or aralkyl group; R2 is H or lower alkyl group).
EXAMPLE: 8-Ethoxy carbonyl-6-hydroxyethyl-6,9-dihydro-9-OXO-1H-pyrzolo[3,4-f] quinoline.
USE: Antibacterials effective against Gram-positive and Gram-negative bacteria.
PROCESS: A pyrazoquinoline of formula II is reacted with the corresponding hydroxy lower alkyl halide, lower alkenyl halide, or aralkyl halide in the presence of a base, e.g. NaHCO3, CaCo3, etc. or a deacidification agent in a solvent, e.g. methanol, ether, etc., which will not take part in the reaction, to give the pyrazoloquinoline of formula I.
