Abstract

1464902 D-Penicillanine HEYL & CO CHEMISCH - PHARMAZEUTISCHE FABRIK 1 Aug 1974 [19 March 1974] 34086/74 Heading C2C D-Penicillanine or an acid addition salt thereof is prepared by (i) hydrolytically degrading a 10 to 40% by weight crude aqueous concentrate of a penicillin obtained by a fermentation process (ii) optionally decarboxylating the penicilloic acid obtained to form a penilloic acid (iii) reacting the penicilloic or penilloic acid obtained with an organic solution of 0À3 to 0À7 moles of a mercuric salt per mole of acid (iv) separating the penicillanine mercuric mercaptide formed, suspending it in water or an organic solvent and decomposing it with H 2 S and (v) recovering D-penicillanine or its acid addition salt from the filtrate after removal of the deposit formed during decomposition. The penicillin used was the potassium salt of benzyl penicillin.
