Procedure

To a solution of 250 ml. of anhydrous ethanol and 0.12 moles of sodium sulfite is added 0.1 moles of α-chloro-γ-(2'-chloro-4-biphenylyl) butyric acid, sodium salt. The reaction mixture is stirred for 15 hours, filtered and the residue worked with ethanol. The filtrate is evaporated to dryness to obtain α-sulfo-γ-(2'-chloro-4-biphenylyl)butyric acid, disodium salt.
