(2S)-2-(((benzyloxy)carbonyl)amino)-3,3-dimethylbutanoic acid → HCID 70047483, compound

Participants

Reaction Steps

In a manner analogous to that described in Example 6, 68 mg (0.26 mmol) of N-benzyloxycarbonyl-3-methyl-L-valine were coupled with 90 mg (0.26 mmol) of 2(S)-[3(S)-amino-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-1(R)-cyclohexanecarboxamide to give 40 mg of 2(S)-[3(S)-[[N-(benzyloxycarbonyl)-3-methyl-L-valyl]amino]-2(R)-hydroxy-4-phenylbutyl]-N-tert.butyl-1(R)-cyclohexanecarboxamide as a white solid of melting point 90° C. (decomposition); MS m/e 594 [M+H]+.
