Procedure

5-t-Butyldimethylsilyloxymethyl-1-[(2'-carbomethoxybiphenyl-4-yl)methyl]-4-chloro-2-(cis-pent-1-en-1-yl)imidazole (100 mg) was desilylated with fluoride by procedures familiar to one skilled in the art. Flash chromatography in 1:1 hexane/ethyl acetate yielded 65 mg of a viscous, colorless oil. NMR (200 MHz, CDCl3) δ 7.85 (d, 1H), 7.55 (t, 1H), 7.42 (t, 1H), 7.28 (m, 3H), 7.05 (d, 2H), 6.11 (d, 1H), 5.92 (d of t, 1H), 5.30 (s, 2H), 4.57 (d, 2H), 3.64 (s, 3H), 2.69 (quart., 2H), 1.62 (t, 1H), 1.47 (sext., 2H), 0.92 (t, 1H).
