실험 절차
A solution of 3-ethyl-N-methyl-1H-indole-2-carboxamide (970 mg, 4.80 mmol) in dioxane was added slowly to an ice-cooled solution of lithium aluminium hydride (273 mg, 72 mmol) in dioxane (10 mL). The mixture was stirred at reflux overnight. Excess lithium aluminium hydride was quenched with 15% NaOH (2 mL) and the mixture separated. The aqueous phase was washed twice with ethyl acetate and the combined organic phases dried to afford the title compound (550 mg, 61%). 1H NMR (400 MHz, DMSO-d6) δ 10.59 (s, 1H), 7.42 (d, J=8 Hz, 1H), 7.25 (d, J=7.6 Hz, 1H), 7.00 (t, J=7.2 Hz, 1H), 6.89 (t, J=7.2 Hz, 1H), 3.75 (s, 2H), 2.66 (q, J=7.5 Hz, 2H), 2.27 (s, 3H), 1.14 (t, J=7.6 Hz, 3H).
