Procedure

Title compound 4 (0.508 g, 1.48 mmol) was dissolved in formic acid (5.0 mL) and the mixture was cooled at 4° C. Sodium borohydride (0.502 g) was added and the reaction mixture was stirred at room temperature for 90 min. The mixture was diluted in water (50 mL) and solid sodium bicarbonate was added until alkaline (pH=8-9). This mixture was extracted twice with ethyl acetate. The combined organic extracts were washed with water and brine, dried over sodium sulfate and evaporated. The crude was purified by flash chromatography with 10% ethyl acetate in hexanes to afford title compound 7 (408 mg, 77%) as a colorless oil. LRMS (ESI): (calc) 359.15. (found) 360.3 (MH)+.
