Potassium carbonate (66.2 mmol) was added in one portion to a solution of 6-bromo-2-(trifluoroacetyl)-1,2,3,4-tetrahydroisoquinoline and 8-bromo-2-(trifluoroacetyl)-1,2,3,4-tetrahydroisoquinoline (17.6 mmol) in MeOH (130 mL) and water (45 mL). The reaction mixture was allowed to stir at rt overnight and then diluted with EtOAc (150 mL). The mixture was washed with brined, dried over Na2SO4, filtered, and concentrated to give 6-bromo-1,2,3,4-tetrahydroisoquinoline and 8-bromo-1,2,3,4-tetrahydroisoquinoline (5.0 g, 100%) as a white solid.
