In a manner analogous to that described in Example 6, 73 mg (0.29 mmol) of N-benzyloxycarbonyl-L-valine were coupled with 100 mg (0.29 mmol) of 2(S)-[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-1(R)-cyclohexanecarboxamide to give 80 mg of 2(S)-[3(S)-[[N-(benzyloxycarbonyl)-L-valyl]amino]-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-1(R)-cyclohexanecarboxamide as a white solid; MS m/e 580 [M+H]+.
