Methanesulphonyl chloride (0.1 g, 1.29 mmole) was reacted with N-ethyl-N-(6-aminoquinol-2-ylmethyl)-4-methanesulphonamidophenethylamine (see Preparation 11B--0.51 g, 1.23 mmole) in pyridine similarly to the procedure of Example 2, giving the free base of the title compound as a gum. The gum was dissolved in ethyl acetate and the solution was diluted with ethereal hydrogen chloride and evaporated to dryness. The residue was triturated with ether to give the title compound as a foam, yield 0.06 g, m.p. 96°.
