13.0 mg (0.50 mmol) 95% sodium hydride were given to a solution of 108 mg (0.50 mmol) 4-(4-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 overnight. After addition of 10 ml water the resulting precipitate was washed 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 167 mg colorless powder that was further purified by HPLC-MS to give 75 mg (29%) colorless powder.
