Procedure

4-Chloro-8-ethyl-quinoline-3-carboxylic acid ethyl ester (250 mg, 0.95 mmol) was treated with cyclopentylamine following general procedure B to afford 4-cyclopentylamino-8-ethyl-quinoline-3-carboxylic acid ethyl ester (250 mg). Thus obtained amino-ester was hydrolyzed to the corresponding acid in quantitative yield using general procedure D and then transformed into the corresponding ethylamide (180 mg) following general procedure E.
