Reaction Steps

3.0 g 2-Chloro-4-{4-methyl-2-[2-(4-trifluoromethyl-phenyl)-ethyl]-oxazol-5-ylmethoxy}-benzonitrile were dissolved in a mixture of 20 ml tetrahydrofuran and 20 ml methanol. 9.91 g hydroxylamine hydrochloride were added followed by the addition of 19.9 ml triethylamine. The reaction mixture was stirred at 65° C. overnight. The solvents were removed in vacuo and the resulting residue poured into water and extracted five times with ethylacetate. The combined organic extracts were washed with brine, dried over MgSO4 and the solvent was evaporated in vacuo to obtain 4.4 g crude 2-chloro-N-hydroxy-4-{4-methyl-2-[2-(4-trifluoromethyl-phenyl)-ethyl]-oxazol-5-ylmethoxy}-benzamidine which was used without further purification.
