Versuchsvorschrift

To a solution of ethyl 2-(7-hydroxy-8-methyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (100 mg, 0.366 mmol) in DMF (3 mL) was added cesium carbonate (155 mg, 0.476 mmol), followed by 5-(chloromethyl)-2-isopropoxybenzonitrile (100 mg, 0.476 mmol). The reaction mixture was heated at 65° C. for 15 h and cooled down. The solid was filtered and washed with ethyl acetate. The combined solvent was evaporated, and the residue was purified by column chromatography to give the title compound (130 mg) as a colorless oil. LCMS m/z=447.7 [M+H]+; 1H NMR (400 ME-1z, CDCl3) δ ppm 1.32 (t, J=7.1 Hz, 3H), 1.42 (d, J=6.0 Hz, 6H), 2.25-2.32 (m, 1H), 2.42 (s, 3H), 2.58 (dd, J=16.0, 8.4 Hz, 1H), 2.82-2.92 (m, 2H), 3.73-3.80 (m, 1H), 3.95-4.02 (m, 1H), 4.08-4.15 (m, 1H), 4.20-4.27 (m, 2H), 4.62-4.69 (m, 1H), 4.96 (s, 2H), 6.13 (s, 1H), 6.83 (d, J=8.7 Hz, 1H), 6.97 (d, J=8.7 Hz, 1H), 7.01 (d, J=8.7 Hz, 1H), 7.59 (dd, J=8.6, 2.2 Hz, 1H), 7.63 (d, J=2.1 Hz, 1H).
