Reaction Steps

Reaction 5-(3-bromo-2-methoxy-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole (485 mg, 1.26 mmol), 2.5 M n-BuLi (828 uL, 2.07 mmol), and DMF (494 uL, 6.38 mmol) for 2 h at −40° C. followed by column chromatography on silica gel (EtOAc/hexane 9:1) gave the title compound (240 mg, 47%) as a yellow oil. 1H NMR (300 MHz, CDCl3) δ0.00 (s, 9H), 0.94 (t, 2H, J=9.0 Hz), 3.61 (t, 2H, J=7.5 Hz), 3.93 (s, 3H), 5.83 (s, 2H), 6.86 (d, 1H, J=9.0 Hz), 7.38 (dd, 1H, J=9.0, 3.0 Hz), 7.94 (s, 1H), 8.3 (d, 1H, J=3.0 Hz), 9.89 (s, 1H). ES-MS m/z 413 (M+H).
