実験手順

Prepared using similar procedure described in Example 52-1 with appropriate intermediates and conditions. Intermediate 1 and benzyl-H-tetrazole-5-carbonyl chloride (prepared according to J. Med. Chem. 1986, 29, 538-549) are used instead of intermediates 31 and 32. For coupling reaction, Et3N and DCM are used instead of HATU and DMF. For deprotection, hydrogeneation with Pd on carbon is used instead of TFA.
