Pentanoic acid, 2-(acetylthio)-3-methyl-, (2S,3S)- → 3-[(2S, 3S)-2-Acetylthio-3-methylvalerylamino]-1-ethoxycarbonylmethyl-1H-[1]benzazepin-2-one

Participants

Reaction Steps

0.525 g (2 mmol) of 3-amino-1-ethoxycarbonylmethyl-1H-[1]benzazepin-2-one and 0.418 g (2.2 mmol) of (2S,3S)-2-acetylthio-3-methylvaleric acid were reacted in the same manner as that of Example A-2. Thus, 0.42 g of the title compound was obtained as a colorless amorphous product. Yield 48%.
