실험 절차
A solution of 4-chloromethyl-2-[2-(4-trifluoromethanesulfinyl-phenyl)-vinyl]-oxazole (0.5 g, 1.5 mmol) and sodium 4-bromobenzenesulfinate (0.72 g, 3 mmol) in N,N-dimethyl formamide (20 ml) was stirred for 3 h at 60° C. After cooling the mixture was poured onto water, extracted with ethyl acetate (3×50 ml), the combined organic layers were washed with water, dried over sodium sulfate, concentrated in vacuo and crystallized from ether yielding 4-(4-bromo-benzenesulfonylmethyl)-2-[2-(4-trifluoromethanesulfinyl-phenyl)-vinyl]-oxazole as white crystalline product. Yield 0.6 g (77%)
