Procedure
The title compound is prepared from 5-(1-benzyl-2-(pyridin-3-yl)-1H-imidazol-5-yl)-4-methyl-2-phenylthiazole (Example 71) in a similar manner as described in Tetrahedron Letters, 2008, 64(26), 6060-6072. In this case, 5-(1-benzyl-2-(pyridin-3-yl)-1H-imidazol-5-yl)-4-methyl-2-phenylthiazole in methanol is debenzylated by hydrogenation under an atmospheric pressure of hydrogen using a balloon with vigorous stirring for 70 h under reflux. The reaction mixture is filtered through Celite, filtered and concentrated under reduced pressure. The residue is chromatographed on silica to give the title compound.
