Benzylpenicilloic acid α-amides (1a-d) prepared by aminolysis of benzylpenicillin were treated with arylamines (2, 7, 9 and 13a-f) in the presence of acetic acid to give D-penicillamine (3) in good yield and high purity. The structures pf the by-products formed in these reactions were also determined.
