methyl 7-methoxy-1H-indole-4-carboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a cooled (ice/water bath) solution of methyl 7-(methyloxy)-1H-indole-4-carboxylate (350 mg, 1.706 mmol) in DMF (20 mL) was added sodium hydride (56.0 mg, 2.217 mmol). After 10 minutes added 2-iodopropane (0.188 mL, 1.876 mmol). The reaction was stirred at RT for 1 h, followed by heating at 50° C. for 2 h. The reaction was then cooled in an ice water bath and more sodium hydride (56.0 mg, 2.217 mmol) and 2-iodopropane (0.188 mL, 1.876 mmol) were added. The reaction was heated at 50° C. for 3 h, at which time it was concentrated. The residue was dissolved in DCM and washed with water and brine, dried over MgSO4, filtered and concentrated to give 400 mg of the title compound. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.49 (d, 6 H), 3.95 (s, 3 H), 4.01 (s, 3 H), 5.46 (dt, J=13.39, 6.69 Hz, 1 H), 6.66 (d, J=8.34 Hz, 1 H), 7.15 (d, J=3.03 Hz, 1 H), 7.34 (d, J=3.28 Hz, 1 H), 7.87 (d, J=8.34 Hz, 1 H).
