Procedure
To a suspension of N-[1-(3,4-dichloro-phenyl)-1H-imidazol-4-ylmethyl]-acetamide (1.1 g, 3.7 mmol) in 1,2 dimethoxyethane (11 ml) was added Lawesson's reagent (0.82 g, 2.0 mmol) and the mixture refluxed for 90 min. After addition of saturated NaHCO3 solution (50 ml) and extraction with CH2Cl2 (3×100 ml) the combined organic phases were dried (Na2SO4), concentrated and the obtained crude product was chromatographed [silica, elution with gradient CH2Cl2 to 100% (CH2Cl2/MeOH=9:1)]. The title compound was obtained as a brown crystalline material (0.75 g, 68%). Mp. 166-170° C. (MeOH/CH2Cl2), MS: m/e=299 (M+).
