Participants

Reaction Steps

The product from Example 46A (1.5 g, 4.33 mmoles) in ethanol (10 mL) and tetrahydrofuran (4 mL) was treated with sodium borohydride (0.164 g, 4.33 mmoles). After stirring for 30 minutes at room temperature, the mixture was quenched with saturated ammonium chloride and diluted with diethyl ether. The diethyl ether was washed with saturated ammonium chloride, brine, dried with sodium sulfate, filtered and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, 10:1 to 4:1 hexanes:ethyl acetate) to provide the title compound (1.39 g, 92%). MS (ESI+) m/z 348 (M+H)+.
