Versuchsvorschrift

In benzene (4 ml) was dissolved 7-(2-chlorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one (272 mg), and to the solution was added m-chloroperbenzoic acid (267 mg). The mixture was stirred at room temperature for 1 hour, and to the mixture were added ethyl acetate (70 ml), saturated sodium hydrogen carbonate solution (30 ml) and sodium nitrite (100 mg). The mixture was shaken, and the separated upper layer was washed with water and concentrated under reduced pressure. The residue was washed with ethyl acetate and dried to give 7-(2-chlorophenyl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one-1-oxide (205 mg) as pale yellow crystals.
