실험 절차

A solution of the product from example 1 (140 mg, 0.58 mmol) in THF (2 ml) was treated with bromine (0.50 ml). After 10 min at RT, the reaction was diluted with chloroform and the product was filtered. The filtered product was taken up in methanol and treated with 1M HCl in ether and concentrated. The residue was triturated with ether to provide 160 mg of 7,9-dibromo-β-carboline hydrochloride.
