Procedure

The title compound was prepared as a mixture of diastereomers from 1-(tert-butoxycarbonyl)-3,3-dimethyl-dl-proline (61 mg, 0.25 mmol) and N-[5-chloro-2-(1H-tetrazol-1-yl)benzyl]-L-prolinamide (Example 26, Step B, 95 mg, 0.25 mmol) essentially according to the EDC coupling procedure described in Example 39, Step D. The diastereomeric products were separated by reverse phase HPLC and were carried on directly to deprotection.
