Reaction Steps

As described previously for the preparation of 1-Ethyl-2-(2-thiazol-2-yl-imidazol-1-ylmethyl)-6-trifluoromethyl-1H-imidazo[4,5-c]pyridine, nucleophilic displacement of the 2-chloromethyl-3-ethyl-6-trifluoromethyl-3H-imidazo[4,5-c]pyridine with the same 2-(1H-imidazol-2-yl)-thiazole followed by usual work provides 3-ethyl-2-{[2-(1,3-thiazol-2-yl)-1H-imidazol-1-yl]methyl}-6-(trifluoromethyl)-3H-imidazo[4,5-c]pyridine. 1H NMR (CD3OD) δ 9.02 (s, 1H), 7.89 (s, 1H), 7.70 (d, J=3 Hz, 1H), 7.52 (d, J=3.3 Hz, 1H), 7.46 (d, J=1.5 Hz, 1H), 7.19 (d, J=1.5 Hz, 1H), 6.29 (s, 2H), 4.56 (q, J=7.5 Hz, 2H), 1.52 (t, J=7.5 Hz, 3H) m/z 379 [M+1]
