2-(4-Iodo-2-methoxy-pyridin-3-yl)-4-methyl-5-phenyl-imidazol-1-ol (0.093 g, 0.228 mmol) was reacted as described for the synthesis of 4-[2-(3-chloro-phenyl)-2-hydroxy-ethylamino]-3-(4-ethyl-5-phenyl-1H-imidazol-2-yl)-1H-pyridin-2-one except that the compound was first treated with titanium(III) chloride and then hydrochloric acid/acetic acid. The title material was obtained (0.013 g, 14%) as a brown solid.
