실험 절차

Ethyl 2-(7-methoxy-8-methyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-ylidene)acetate (351 mg, 1.23 mmol) was dissolved in EtOAc (6 mL) and ethanol (6 mL), 10% Palladium on carbon (120 mg) was added. The reaction was degassed and charged with hydrogen, then stirred at room temperature overnight. The solid was filtered off. The filtrate was concentrated to give the title compound (320 mg) as an oil without further purification. LCMS m/z=288.2 [M+H]+; 1H NMR (400 MHz, CDCl3) δ ppm 1.32 (t, J=7.1 Hz, 3H), 2.25-2.32 (m, 1H), 2.40 (s, 3H), 2.58 (dd, J=16.0 and 8.6 Hz, 1H), 2.80-2.95 (m, 2H), 3.73-3.80 (m, 1H), 3.85 (s, 3H), 3.95-4.02 (m, 1H), 4.06-4.18 (m, 1H), 4.18-4.26 (m, 2H), 6.11 (s, 1H), 6.84 (d, J=8.6 Hz, 1H), 7.02 (d, J=8.6 Hz, 1H).
