Reaction Steps

To (3S,4S)-1-amino-3-hydroxy-4-t-butyloxycarbonylamino-5-cyclohexylpentane (30.8 mg, 0.102 mmol) in dry methylene chloride (3 mL) at 0° C. was added 4-methylpentanoyl chloride (17.0 microliters, 0.123 mmol) and triethylamine (20.0 microliters, 0.143 mmol). The mixture was stirred at 0° C. for 1 hour, evaporated, taken up in methanol (3 mL) and treated with 1M NaOH (1 mL). After stirring for 1 hour, the mixture was diluted with ether, washed sequentially with 0.5M H3PO4, saturated NaHCO3 solution, and brine, and then dried over Na2SO4 and evaporated to afford 41.0 mg (100%) of the desired product as an oil.
