الإجراء التجريبي

A mixture of 3-amino-5-chlorophenol (0.46 g), 3-(4-chlorobenzyl)pentane-2,4-dione (0.72 g), and p-toluenesulfonic acid monohydrate (0.26 g) was heated at 160° C. for 2 hours. The mixture was cooled to room temperature, diluted with methanol (5.0 mL) and sonicated. The resulting precipitate was collected by filtration, washed with methanol and dried to afford a 50:50 mixture of title compound and 5-chloro-3-(4-chlorobenzyl)-2,4-dimethylquinolin-7-ol as an off-white solid, 0.67 g.
