実験手順
To a solution of 1,2,3,4-tetrahydroisoquinoline (15 g, 0.11 mol) in MeCN (100 mL) was added K2CO3 (30.7 g, 0.23 mol) at 0° C. 2-(bromomethyl)oxirane (17 g, 0.12 mol) was added to the reaction after 1 h. The solution was stirred at 22° C. for 16 h at which time the solids were filtered and washed with MeCN. The solution was concentrated and the residue was used in the next step without further purification (17 g, Yield 78%). LCMS (m/z): 190.1 (M+1).
