Reaction of 4-(4-nitro-phenyl)-1-(2-trimethylsilanyl-ethoxymethyl)-1H-imidazole (170 mg, 0.53 mmol), 0.53 M LDA (1 mL, 0.53 mmol), and DMF (232 uL, 1.60 mmol) for 4 h at −40° C. followed by column chromatography on silica gel (EtOAc/hexane 9:1) gave the title compound (55 mg, 30%) as a yellow oil. 1H NMR (300 MHz, CDCl3) δ 0.00 (s, 9H), 9.95 (t, 2H, J=9.0 Hz), 3.63 (t, 2H, J=9.0 Hz), 5.82 (s, 2H), 7.79 (s, 1H), 7.98 (d, 2H, J=9.0 Hz), 8.27 (d, 2H, J=9 Hz), 9.89 (s, 1H).
