실험 절차

The sodium salt of 3-amino-4-methylthiophene-2-carboxylic acid (7.2 g, 0.04 mol) and ethyl 8-methoxy-4-chloroquinoline-3-carboxylate (5.39 g, 0.02 mol) in toluene (75 ml), ethanol (55 ml) and glacial acetic acid (10 ml) were stirred at room temperature for five days. The solvents were removed by evaporation at reduced pressure to give a dark-green slurry. 10% aqueous sodium carbonate was added and the insoluble solid filtered off, washed well with water and dried. This material was crystallised from ethyl acetate (with charcoaling) to give the title compound as pale yellow crystals (2.15 g), m.p. 162°-164°.
