Reaction Steps

To a solution of methyl 4,5-dihydro-1H-pyrrolo[2,3-f]isoquinoline-3-carboxylate E1 (0.44 mmol) in dry DMF (5 mL) NaH (0.52 mmol) was added. The reaction mixture was stirred at rt for 2 h. After cooling to 0° C., trifluoroethyl triflate (0.52 mmol) in DMF (5 mL) was added dropwise. The mixture was maintained at rt overnight and then poured into icy water and extracted with DCM. The organic layer was dried (Na2SO4) and concentrated. Purification by chromatography on silica gel (eluant: DCM/acetone 9:1) afforded the title compound (65% yield). ESI (+) MS: m/z 311 (MH+). 1H NMR: 2.82 (t, J=7.70, 2H), 2.92 (t, J=7.70, 2H), 3.76 (s, 3H), 5.41 (q, J=8.90, 2H), 7.56 (d, J=5.24, 1H), 7.75 (s, 1H), 8.41 (d, J=5.24, 1H), 8.44 (s, 1H).
