Reaction Steps

To a stirring solution of 1,2,3,4-tetrahydroisoquinoline (15 g, 0.11 mol) in MeCN (100 mL) at 0° C. was added K2CO3 (30.7 g, 0.23 mol), then 2-(bromomethyl)oxirane (17 g, 0.12 mol) added slowly over a period of 1 h. After the addition the solution was stirred at 21° C. for 12 h. The resulting solid was then removed by filtration and washed with MeCN and the combined organic filtrate was concentrated under reduced pressure to give the crude product. This residue was used into next step without further purification (17 g, Yield: 78%). LCMS (m/z): 190.1 (M+1).
