(ii') The salt is taken up in 0.1 N HCl, and the obtained solution is then extracted with ethyl acetate. The aqueous phase is made basic by the addition of a sodium carbonate solution and extracted with ethyl acetate. This last organic extract is then dried and evaporated to dryness to afford a residue which is dissolved in isopropanol. The compound of the title is then precipitated therefrom by the addition of hydrogen chloride saturated isopropanol and is recovered by filtration M.p. 228°-230° C.; [α]=-79.0° (c=1.4%, MeOH).
