    Abstract: Quinoline derivs. of formula (I) and their pharmaceutically acceptable acid addn. salts are new. In (I), R1=C1-3 alkyl; R2 and R3 each = H or lower alkyl; X=N, C-H or C-halogen; Y=H, halogen or amino. Also claimed is the prepn. of (I) which comprises reacting a carboxylic acid deriv. of formula (II) with a cpd. of formula (III) at room temp. -200 deg.C for 1-8 hr(s). The cpds. (I) have a broad spectrum antibacterial activity, low toxicity and high bioavailability.
