Hydroxyamine hydrochloride (174 mg) was dissolved in dimethylsulfoxide (2 ml) and 28% solution of sodium methoxide in methanol (0.125 g) was added into it. The mixture was stirred for ten minutes at room temperature. 2-{2-{[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy}-pentanenitrile (224 mg) was added into the solution and the resulting mixture was stirred at 80° C. for an hour. The reaction mixture was collected and diluted with water and was extracted with ethyl acetate. The organic layer was washed with brine and was dried over magnesium sulfate. Concentration gave 2-{2-{[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy}pentanamide oxime as an amorphous solid (266 mg).
