13.0 mg (0.50 mmol) 95% sodium hydride were given to a solution of 130 mg (0.50 mmol) 4-{4-[2-(2-Hydroxyethyl)-imidazol-1-yl]-butyl}-phenol in 4.0 ml DMF and stirred for 15 min. 168 mg (0.50 mmol) 4-chloromethyl-2-[2-(4-trifluoromethanesulfinyl-phenyl)-vinyl]-oxazole were added and stirring continued at r.t. overnight. After addition of 10 ml water the resulting precipitate was washed twice with water, 10 ml methanol/water 1:1 and with diethyl ether. The residue was purified by chromatography on silica gel (eluent: ethyl acetate/methanol 9:1) to yield 99 mg colorless powder that was further purified by HPLC-MS.
