90% | With N-Bromosuccinimide; In N,N-dimethyl-formamide; for 12.0h;Reflux; | 20 g (62.6 mmol) of compound K were suspended in 200 ml of DMF,To this was added 12.93 g (72.67 mmol) of NBS little by little,And the mixture was refluxed and stirred for 12 hours.then,Add distilled water to complete the reaction,The mixture was extracted with dichloromethane,And the organic layer thus obtained was filtered through silica gel.Then,After removing the organic solution,The solid product was subjected to silica gel column separation with hexane: dichloromethane = 7: 3 (v / v)Recrystallization from methylene chloride and n-hexane,22.4 g (90%) of compound L was obtained. |
88% | With N-Bromosuccinimide; In N,N-dimethyl-formamide; at 20.0℃; for 12.0h; | 37 g (114 mmol) of the compound 9- (biphenyl-3-yl) -9H-carbazole and 22 g (126 mmol) of NBS were suspended in 600 mL of dimethylformamide, followed by stirring at room temperature for 12 hours. The reaction solution was added as distilled water and stirred at room temperature for 6 hours. The filtrate was filtered under reduced pressure, the solid was added to methyl alcohol and stirred at room temperature again. After filtration under reduced pressure, compound 9- (biphenyl-3-yl) -3-bromo-9H-carbazole, 40g (yield: 88%) was obtained. |
88% | With N-Bromosuccinimide; In N,N-dimethyl-formamide; for 12.0h;Cooling with ice; Darkness; | Compound 2-46-6 (19.1 g, 60 mmol) and 100 mL of N,N-dimethylformamide were added into a 250 mL single-necked flask, and 60 mmol N,N-dimethylformamide of NBS was added dropwise in an ice bath. The solution was reacted under stirring for 12 hours in the dark, and then the reaction was ended. The reaction solution was poured into 500 mL of water, filtered with suction, and the filter residue was recrystallized, with a yield 88%. http://baike.sogou.com/lemma/ShowInnerLink.htm?lemmaId=600024&ss_c=ssc.citiao.link |
