Abstract

Method comprises hydrogenating 6,6-dibromopenicillanic acid (II) with a mixt. of Cd powder and mineral acid such as H2SO4 or HCl in solvent system comprising water and one of tetrahydrofuran, dioxan, or ethyl acetate, between 0 and 15 deg.C; filtering to remove excess Cd; distilling the filtered 6% to remove the solvent and obtain penicillanic acid 1,1-dioxide (I); neutralising with NaOH or KOH and (e) treating with Na or K 2-ethyl hexanoate in ethyl acetate.
