Procedure

To a solution of N-(3-methylbutyl)-4-[4-(trifluoromethyl)phenyl]-1,3-thiazole-2-amine (1.20 g, 3.82 mmol) in N,N-dimethylformamide (20 mL) was added sodium hydride (60% in oil, 229 mg, 5.73 mmol) and the mixture was stirred for 30 min. Methyl 4-(bromomethyl)benzoate (1.05 g, 4.58 mmol) was added and the mixture was stirred at 60° C. for 1.5 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=97/3-hexane/ethyl acetate=60/40) to give the title compound (1.34 g, yield 76%) as a yellow oil.
