Reaction Conditions

Reaction Steps

To a solution of 3(S)-(t-butyloxycarbonyl)amino-1,2(S)-epoxy-4-phenylbutane (200 mg, 0.76 mmol) in 2 mL of dry isopropanol was added isobutylamine (0.38 mL, 3.8 mmol) and the mixture was stirred for 5 h at 50° C. The mixture was concentrated under reduced pressure and dried in vaccuo to give 230 mg of 2(S)-hydroxy-3(S)-(t-butyloxycarbonyl)amino-1-isobutylamino-4-phenylbutane
