Versuchsvorschrift

A solution of 3-(4-chlorobenzyl)-5-hydroxy-4,7-dimethyl-1H-quinolin-2-one (1.8 g) in phosphorus oxychloride (9.0 mL) was heated at 180° C. in a microwave reactor for 15 minutes. The solution was poured onto a mixture of ice and water and the resulting precipitate collected by filtration, washed with water and then dried to afford title compound, 2.3 g.
