실험 절차

To a cooled (0° C.) solution of 2-(3-morpholin-4-ylmethyl-1H-indol-6-yloxy)-benzothiazole (280 mg, 0.77 mmol) in DMF (4 mL) was added NaH (95%, 29 mg, 1.15 mmol) and the resulting suspension was stirred (0° C., 15 min) then warmed (rt, 30 min). The reaction mixture was cooled (0° C.) and treated with methyliodide (72 μL, 163 mg, 1.15 mmol) and then warmed (rt, 30 min). The reaction mixture was partitioned with EtOAc and brine (20 mL each). The organic layer was dried, filtered and concentrated in vacuo. The resulting residue was purified by silica gel flash chromatography using MeOH:DCM (0-20%) to provide the title compound as a clear oil (126 mg, 43%). MS (ESI): mass calcd. for C21H21N3O2S, 379.4; m/z found, 380.1 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.79 (d, J=8.6, 1H), 7.76 (d, J=7.7, 1H), 7.66 (d, J=8.0, 1H), 7.41-7.38 (m, 1H), 7.29 (d, J=2.1, 1H), 7.29-7.25 (m, 1H), 7.12 (dd, J=8.6, 2.1, 1H), 3.77 (5, 3H), 3.74 (t, J=4.6, 4H), 3.71 (5, 2H), 2.53 (br s, 4H).
