Reaction Steps

A solution of 4-methyl-2-(2H-pyrazol-3-yl)-thiazole-5-carboxylic acid benzylamide (0.2 g, 0.61 mmol) in dimethyl sulfoxide (5 mL) was treated with 4-fluorophenoxyethyl bromide (0.14 g, 0.67 mmol) and potassium carbonate (0.30 g, 2.0 mmol), and the reaction mixture was heated to 90° C. for 16 hr. The reaction mixture was cooled to room temperature, diluted with ethyl acetate (50 mL), and washed with brine (2×50 mL). The organic phase was dried (Na2SO4) and evaporated. The residue was purified by preparative thin layer chromatography over silica gel (methylene chloride:methanol, 95:5) to provide 2-{1-[2-(4-fluoro-phenoxy)-ethyl]-1H-pyrazol-3-yl}-4-methyl-thiazole-5-carboxylic acid benzylamide (0.071 g, 51% yield) as a white solid.
