Procedimiento

The reaction is carried out at 25° C. and pH 7.5 in a fixed bed reactor. 10 ml of an aqueous solution of a mixture 0.2 M 7-ADCA and 0.2 M D-phenylglycinamide are passed through a column with 0.5 ml of the immobilized penicillin amidase. During the reaction, the pH is kept constant by adding HCl in an attached stirred reservoir container. Samples are taken and analyzed by HPLC as shown in example 5 at particular time intervals.
