Boron tribromide → 6-Isoquinolinol, 7-bromo-

Participants

Reaction Steps

3.6 mL (9.5 g, 37.8 mmol) of BBr3 were added at 0° C. to a solution of 4.5 g (18.9 mmol) 7-bromo-6-methoxy isoquinoline in 30 mL dichloromethane and stirred for 18 h at room temperature. Aqueous NaHCO3-solution was added to adjust the pH to 8. Extraction with chloroform/isopropanol (3/1) followed by drying over sodium sulfate and removal of the solvents gave 2.7 g (64%) of compound 1.
