실험 절차

A solution of ethyl 5-nitro-3-phenyl-1H-indole-2-carboxylate (1.0 g, 3.23 mmol) and iodomethane (2.5 mL, 40.2 mmol) in DMF (25 mL) was treated with Cs2CO3 (3.26 g, 10 mmol) and stirred for 16 h. The reaction was quenched by addition of water and the solid was collected and dried to yield ethyl 1-methyl-5-nitro-3-phenyl-1H-indole-2-carboxylate (I13064-48) as a yellowish solid (1.1 g, 100%): 1H NMR (DMSO-d6) δ 1.03 (t, J=7.0 Hz, 3 H), 4.09 (s, 3 H), 4.18 (q, J=7.0 Hz, 2 H), 7.40-7.55 (m, 5 H), 7.90 (d, J=9.2 Hz, 1 H), 8.23 (dd, J=9.2, 2.3 Hz, 1H), 8.32 (d, J=2.3 Hz, 1 H); MS (EI) m/z 325.2 (MH+).
