Procedure

To a solution of 180 mg of 4-[4-butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-2-trifluoromethyl-benzonitrile in 5 mL of tetrahydrofuran and 10 ml of methanol was added 267 mg of hydroxylamine hydrochloride followed by 0.55 mL of triethylamine. The resulting mixture was heated to 60° C. overnight. The solvents were removed in vacuo, the resulting residue was poured into water and extracted with ethylacetate. The organic extracts were dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel (heptane 1/ethyl acetate 1) to give 90 mg of 4-[4-butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-N-hydroxy-2-trifluoromethyl-benzamidine and 50 mg of 4-[4-butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-ylmethoxy]-2-trifluoromethyl-benzamide.
