Reaction Steps
A solution of ethyl 3,7-dimethyl-1H-indole-2-carboxylate (1.84 g, 8.4 mmol) in THF (20 mL) was added to an ice-cooled solution of 1.0 M LAH in THF (17.8 mL 17.8 mmol) and stirred overnight. The reaction was quenched with ethyl acetate (5 mL) and 15% aqueous sodium hydroxide (5 mL), filtered through celite and evaporated in vacuo. The crude reaction was chromatographed over silica gel eluting with methanol/dichloromethane (1%) to afford the title compound (440 mg, 30%). 1H NMR (400 MHz, CDCl3) δ 8.39 (s, 1H), 7.39 (d, J=7.7 Hz, 1H), 7.06 (t, J=7.2 Hz, 1H), 6.99 (d, J=7.1 Hz, 1H), 4.82 (s, 2H), 4.11 (q, J=7.1 Hz, 2H), 2.45 (s, 3H), 2.28 (s, 3H), 1.26 (t, J=7.1 Hz, 3H).
