Hydrogen Bromide → 5-(Bromomethyl)-1H-indazole--hydrogen bromide (1/1)

Participants

Reaction Steps

1H-indazole-5-ylmethanol (100 mg, 0.675 mmol) was added to a 48% aqueous hydrogen bromide solution (2.0 ml) at room temperature and stirred at room temperature for 15 hours and then at 50° C. for 5 hours. Subsequently, the reaction solution was filtered and the resulting solid was dried under reduced pressure to obtain 5-(bromomethyl)-1H-indazole hydrobromide (156 mg, 79%).
