Reaktionsschritte
3.52 g (0.01 mole) of benzylpenicilloic acid, 3.70 g (0.03 mole) of m-anisidine and 20 ml of toluene were added to a solution of 3.60 g (0.06mole) of acetic acid in 30 ml of water. The mixture was heated under reflux, with stirring, for 4 hours in a nitrogen atmosphere. The reaction mixture was then treated as described in Example 9 to give D-penicillamine as colorless crystals: yield 1.07 g (71.8%), m.p. 201°-202° C.
