Procedure

To a solution of 2-((3-bromophenoxy)methyl)oxirane (1.5 g, 6.55 mmol) in MeOH (15 mL) was added 1,2,3,4-tetrahydroisoquinoline (1.0 g, 7.86 mmol) at 20° C. The mixture was heated at reflux temperature for 16 h, until the reaction was shown to be complete. The mixture then was concentrated to provide the crude which was purified using column chromatography on silica gel producing the desired 1-(3-bromophenoxy)-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (1.8 g, 78.3%) as colorless oil. LCMS (m/z): 362.1 (M+1).
