1.5 gm (5 millimols) of [1-(2'-fluoro-4-biphenylyl)-ethylsulfinyl]-acetic acid, m.p. 164°-165° C., were stirred with 1.05 gm of potassium carbonate and 0.9 ml of n-butyl bromide in 15 ml of dimethyl sulfoxide for 60 hours. The mixture was subsequently diluted with water, and the reaction product was extracted with toluene. After washing, drying and evaporating the extract, the residue (1.7 gm) was recrystallized from cyclohexane. Yield: 1.2 gm (67% of theory); m.p.: 72°-74° C.
