1-Bromo-Pyrene Use and Manufacturing
A solution of NBS (187 mg, 1.05 mmol) in dry DMF (5 mL) was added to a solution of pyrene (252 mg, 1.0 mmol) in dry DMF (10 mL) and stirred at room temperature 24 h [20]. After reaction, the mixture was poured into water (50 mL) and extracted with dichloromethane (100 mL). The extract was washed well with water, dried (MgSOIn the 500 ml three-neck flask, pyrene (20.2 g, 0.1mol ) was dissolved in the 200ml CHStep 1: Under nitrogen protection conditions, Pyrene 1g (4.9mmol)And 974 mg (5.5 mmol) of benzyltrimethylammonium tribromide (NBS)Dissolved in 50 ml of dichloromethane, The mixture was stirred at room temperature for 5 hours, filter, Recrystallization from methylene chloride and n-hexane, 1-bromopyrene (1.08 g) was obtained in a yield of 78percentWeigh 10g pyrene and 9g NBS dissolved in 100mL chloroform, NPyrene (2 g, 9.9 mmol), NBS (1.78 g, 10 mmol) were dissolved in 20 mL of CHClPyrene (404 mg, 2 mmol), Potassium bromide (143 mg, 1.2 mmol), Acetic acid 9ml, water 1ml, Dichloromethane 5ml of mixed Combined solution followed by adding with a condenser, In a three-necked flask of a thermometer, Transferred to a constant temperature magnetic stirring water bath, In 15min Slowly add ZnAl
1-Bromopyrene is used in the cleavage of DNA in studies. It is also used in the preparation of DNA base analogs.
