Sodium borohydride → HCID 19385624, compound

Participants

Reaction Steps

A stirred solution of 1.49 g (4.90 mmol) of the product of Step A dissolved in 20 mL of methanol was treated with 0.093 g (2.46 mmol) of sodium borohydride at room temperature. After 5 minutes the reaction mixture was partitioned between ethyl acetate and 1N hydrochloric acid, and the organic layer was separated. The product was washed with water, brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was purified on a silica gel flash chromatography column eluted with 25% ethyl acetate/hexane to afford 1.380 g (92%) of the title compound.
