실험 절차
1 g (4.17 m moles) of (2S)-1-[(S)-alanyl]-2-carboxyperhydroindole, prepared as described in Example 3, Step F, and 4.72 g (19 m mols) of ethyl [(1RS)-1-ethoxycarbonylethylthio]-pyruvate are dissolved in 50 ml of anhydrous ethanol in the presence of 15 g of molecular sieve 4 Å. After 45 minutes's stirring at room temperature, 0.25 g of sodium cyanoborohydride in solution in 2.25 ml of anhydrous ethanol are added within 6 hours.
