실험 절차

A solution of 3-(S)-t-butyloxycarbonylamino-1-ethoxycarbonylmethyl-2,3,4,5,5a,6,7,8,9,9a-decahydro-1H-[1]benzazepin-2,5-dione (2.7 g) and sodium borohydride (0.2 g) in ethanol (100 ml) is stirred at room temperature for 18 hours. The solvent is removed under reduced pressure, and the residue dissolved in dichloromethane (100 ml). The solution is extracted with ice-cold 2N HCl (2×50 ml) and saturated brine (50 ml) and dried over sodium sulfate. The solvent is removed under reduced pressure and the residue triturated with ether to give 3-(S)-t-butyloxycarbonylamino-1-ethoxycarbonylmethyl-5-hydroxy-2,3,4,5,5a,6,7,8,9,9a-decahydro-1H-[1]benzazepin-2-one.
