Versuchsvorschrift
Reaction of 4-(4-nitrophenyl)-1H-imidazole (160 mg, 0.85 mmol), NaH (60%, 33 mg, 0.82 mmol), and SEMCl (158 uL, 0.89 mmol) followed by column chromatography on silica gel (hexane/EtOAC 3:2) gave the title compound (170 mg, 65%) as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 0.00 (s, 9H), 0.94 (t, 2H, J=7.5 Hz), 3.55 (t, 2H, J=7.5 Hz), 5.33 (s, 2H), 7.50 (s, 1H), 7.69 (s, 1H), 7.94 (d, 2H, J=6.0 Hz), 8.26 (d, 2H, J=6.0 Hz).
