Procedure
4-[2-(3,4-Dichlorophenyl)-2-methoxycarbonyl-ethyl]-imidazole-1-carboxylic acid tert-butyl ester was prepared by the procedures described in Example 78, Step 1, substituting 3-tert-butoxycarbonylamino-propionic acid tert-butyl ester with (3,4-Dichlorophenyl)-acetic acid methyl ester and substituting 4-Bromo-1-bromomethyl-2-fluoro-benzene with 4-Bromomethyl-imidazole-1-carboxylic acid tert-butyl ester (prepared from 4(5)-hydroxymethylimidazole hydrochloride according to the literature: J. Med. Chem. 1997, 40, 2208). 1H NMR (CDCl3, 400 MHz) δ 7.96 (s, 1H), 7.42 (s, 1H), 7.38 (d, J=8.0 Hz, 1H), 7.16 (d, J=8.0 Hz, 1H), 7.02 (s, 1H), 4.08 (t, J=7.6 Hz, 1H), 3.66 (s, 3H), 3.32 (dd, J=14.4 Hz, J=8.4 Hz, 1H), 2.92 (dd, J=14.4 Hz, J=6.8 Hz, 1H). LCMS (APCI+) m/z 299, 301, 303 [M-Boc+H]+; Rt=3.72 min.
