Reaction Steps
Reaction of 5-(5,6,7,8-tetrahydro-naphthalen-2-yl)-1-(2-trimethylsilanyl ethoxymethyl)-1H-imidazole (268 mg, 0.82 mmol), 2.5 M n-BuLi (424 uL, 1.06 mmol), and DMF (253 uL, 3.27 mmol) for 2 h at −40° C. followed by column chromatography on silica gel (EtOAc/hexane 9:1) gave the title compound (166 mg, 57%) as a yellow oil. 1H NMR (300 MHz, CDCl3) δ0.00 (s, 9H), 0.94 (t, 2H, J=7.5 Hz), 1.80-1.85 (m, 4H), 2.80-2.83 (m, 4H), 3.60 (t, 2H, J=9.0 Hz), 5.81 (s, 2H), 7.13 (d, 1H, J=6.0 Hz), 7.51 (d, 1H, J=6.0 Hz), 7.57 (s, 1H), 7.60 (s, 1H). 9.88 (s, 1H).
