Conditions

Temperature: 25 °C

Procedure

A solution of Example 283A (50 mg, 0.075 mmol) in dichloroethane (1 mL) was treated with isovaleraldehyde (10 mg, 1.5 equivalents), acetic acid (5 μL, 2 equivalents), and sodium triacetoxy borohydride (32 mg, 2 equivalents), stirred at 25° C. for 16 hrs. The mixture was quenched with 10% NaHCO3 (2 mL) and CHCl3. The organic layer was separated, dried over sodium sulfate, and the solvents were evaporated. The residue was purified using 5% methanol/CHCl3 to give 49 mg (89%) of the title compound.
