A new compound, 3'-fluoro-3'-deoxykanamycin A is now provided, which is active against gram-negative and gram-positive bacteria, including kanamycin-resistant strains of bacteria and is useful as antibacterial agent for therapeutic treatment of bacterial infections. This new compound is produced by a process comprising reacting a 6- azido-2,4-di-O-protected-3,6-dideoxy-3-fluoro-α-D-glucopyranosyl bromide with the 4-hydroxyl group of a 6-0-(2'-0- protected-3'-N-protected-3'-amino-4',6'-di-O-protected-3'-deoxy-a-D-glucopyranosyl)-1,3-bis-N-protected-2-deoxystreptamine, reducing the azido group of the resulting reaction product into an amino group, and removing the remaining protective groups from the reduction product.
