Experimental conditions analogous to those described for Step 4 of Example 60, from 7.00 g (20.5 mmol) of 1-(3-chloro-benzyl)-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid ethyl ester, 200 mL of 1:1 methanol-water mixture and 0.98 g (41.0 mmol) of lithium hydroxide with a work-up consisting only of thorough evaporation of solvents. The residue was directly taken to step 3.
