(1) In a 250 mL single-necked flask was added 2,7-dibromofluorene (9.72 g, 30 mmol), tetra-n-butylammonium bromide (0.08 g, 0.25 mmol), iodomethane (12.8 g, 90 mmol), 10 mL of NaOH solution, and 120 mL of DMSO.The mixture was allowed to react for 5 hours under ultrasonic conditions (100 W). After completion of the reaction, the reaction solution was poured into 500 mL of water, pumped and filtered for 30 min, the filter cake was washed with water and dried to give 10.5 g of light yellow solid in 99% yield. references: [1] Patent: CN106349163, 2017, A.
