반응 단계
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.
