実験手順
A mixture of 35 g (0.17 mol) of 7H-dibenzo[c,e]oxepin-5-one and 30.8 g (0.17 mol) of potassium phthalimide in 330 ml of DMF was heated at 170° C. for 18 h. After cooling, the deposited precipitate was filtered off with suction and introduced into 160 ml of glacial acetic acid. After stirring for 1 h, the mixture was diluted with 650 ml of ice water and the deposited product was filtered off with suction and dried in vacuo. 44.8 g of 2′-phthalimidomethylbiphenyl-2-carboxylic acid were obtained; m.p. 198° C.
