Versuchsvorschrift
In the manner described in example 24, 4-(3-indolyl)-2-oxobutyric acid and L-alanyl-L-proline are condensed in the presence of sodium cyanoborohydride to yield N-[1-carboxy-3-(3-indolyl)propyl]L-alanyl-L-proline. The mass spectrum of the trisilyated material shows a molecular ion at 603 m/e and a M+ -15 peak at 588 m/e.
