Reaction Steps

To a suspension of norharmane (84 mg, 0.50 mmol) in water (3 ml) at RT was added 1M aqueous HCl (1.1 ml, 1.1 mmol). To this homogenous solution was added N-chlorosuccinimide (747 mg, 5.58 mmol) portionwise and the resulting solution was stirred at 60° C. to 70° C. for 3 h. The reaction was partitioned in EtOAc and saturated aqueous NaHCO3 and the organic layer was dried (brine; MgSO4) and then concentrated. The residue was chromatographed (2:3 THF-hexane) on silica gel to give 24 mg of 7,9-dichloro-β-carboline after triturating with (1:1) methylene chloride-hexane, then with hexane.
