Procedure

0.2 g (0.55 mmol) of 2-(2,4-difluoroanilino)-7-methoxy-10,11-dihydrodibenzo[a,d]-cyclohepten-5-one is dissolved in 2 ml of glacial acetic acid, 2 ml of HBr (45%) are added and the mixture is refluxed for 6 h. The solution is hydrolyzed with 200 g of ice and the precipitate is filtered off. The product is obtained in the form of a white powder. C21H15F2NO2 (Mr=351.35)
