Reaction Steps

In a manner analogous to that described in Example 27, from 27 mg of N-[3(S)-[[L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-L-proline tert.butyl ester and 11.3 mg of 2-indolecarboxylic acid there were obtained 15 mg of N-[3(S)-[[N-(2-indolylcarbonyl)-L-asparaginyl]amino]-2(R)-hydroxy-4-phenylbutyl]-L-proline tert.butyl ester; MS: m/e 592 [M+H]+.
