(2S)-2-(((Phenylmethoxy)carbonyl)amino)butanoic acid → 1-(n-Benzyloxycarbonyl-2(s)-aminobutyryl)-2(s)-indolinecarboxylic acid n-butylamide

Participants

Reaction Steps

The process is performed as in Example 15 c), using 0.646 g (2.73 mmol) of N-benzyloxycarbonyl-2(S)-aminobutyric acid prepared as in Example 3 a) and 0.595 g (2.73 mmol) of the amide prepared in step b). An oil is obtained which is recrystallized from CCl4.
