Procedure

To the material isolated in Step A in 2 mL of dichloromethane was added 0.041 mL (0.90 mmol) of iso-butyraldehyde, followed by 0.026 mL (0.45 mmol) of acetic acid and 0.10 g (0.45 mmol) of sodium tracetoxyborohydride. After 16 h at ambient temperature the reaction was diluted with 30 mL of dichloromethane and washed twice with equal volumes of saturated aqueous NaHCO3. The organic layer was dried (Na2SO4) and concentrated in vacuo. Purification by preparative reversed phase BPLC afforded the tide compound.
