Acetyl chloride (4.25 ml, 59.8 mmol) was added, and the reaction mixture was allowed to stir overnight. LC/MS showed mostly product, so the reaction mixture was concentrated yielding 5-(2-bromo-4-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydroisoquinoline hydrochloride (2.32 g, 5.91 mmol). [M+H]+=357.9.
