N-bromobutanimide → 2-[3-bromo-1-(3-fluorobenzyl)-2-methyl-1H-pyrrolo[2,3-c]pyridin-7-yl]-1,2,3,4-tetrahydroisoquinoline hydrochloride

Participants

Reaction Steps

N-Bromosuccinimide (41 mg, 0.23 mmol) and silica gel (100 mg) were added to a solution of 2-[1-(3-fluorobenzyl)-2-methyl-1H-pyrrolo[2,3-c]pyridin-7-yl]-1,2,3,4-tetrahydroisoquinoline hydrochloride (88 mg, 0.23 mmol) prepared in Example 613 in dichloromethane (2 ml). The reaction mixture was stirred for 1 hour and then filtered. The resulting filtrate was concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/n-hexane=1/5, v/v). The resulting product was dissolved in ethyl acetate, saturated with hydrochloric acid gas, and then filtered to give 10 mg of the titled compound as a white solid.
