实验步骤: 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. After cooling the deposited precipitate was filtered off with suction introduced into 160 ml of glacial acetic acid the mixture was diluted with 650 ml of ice water the deposited product was filtered off with suction dried in vacuo

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 9.0 g (0.24 mol) of sodium borohydride were added in portions at 5° C. in the course of 10 min to a suspension of 50.0 g (0.22 mol) of diphenic anhydride in 220 ml of DMF. After stirring at RT for 1 h, the reaction mixture was poured onto 220 ml of 6 M hydrochloric acid, diluted with 750 ml of water and stirred for 2 h. The deposited precipitate was filtered off with suction and 35.0 g of 7H-dibenzo[c,e]oxepin-5-one were obtained; m.p. 131° C. stirred for 2 h The deposited precipitate was filtered off with suction
