Procedure

To a solution of 2-((3-bromophenoxy)methyl)oxirane (1.5 g, 6.55 mmol) in MeOH (15 mL) were added 1,2,3,4-tetrahydroisoquinoline (1.0 g, 7.86 mmol) at 8° C. The mixture was refluxed for 16 h. TLC (PE: EA=2:1) showed that the reaction was completed and the mixture was concentrated to yield crude material which was purified using column chromatography on silica gel to give the desired compound (1.8 g, 78.3%) as colorless oil. LCMS (m/z): 362.1/363.1 [M+H]+/[M+2H]+
