実験手順

To a stirred solution of compound 11 (12.5 g, 57.07 mmol) in chlorobenzene (100 mL), aluminium chloride (37 g, 285.3 mmol) was added in portions over a period of 10 min and heated at 100° C. overnight (TLC chloroform: methanol 9:1, Rf=0.2). The reaction mixture was then cooled to room temperature, poured on crushed ice (300 g) and stirred well for 30 min. The solid separated was filtered washed with water till neutral to pH. It was then washed with hexane (50 mL) and dried to give product 5,7-dihydroxy-4-methyl-1,2-dihydro-2-quinolinone (13, 10.5 g) in 96% yield as a dark brown solid. M.P. >300° C.
