Sodium borohydride → HCID 22988405, compound

Participants

Reaction Steps

Ethyl 2-cyano-3-(4-{2-[4-(isobutyrylamino)phenyl]ethoxy}phenyl)propanoate (0.5 g, 1.22 mmol) was dissolved in methanol (10 ml). Sodium borohydride (0.24 g, 6.34 mmol) was added carefully. The mixture was stirred at room temperature for 4 hours and then evaporated in vacuum to dry. Ethyl acetate and water were added into the residue. After separation, the organic phase was washed with 0.3 M hydrochloric acid, water and brine. The solvent was evaporated in vacuum. Column chromatography of the residue on silica gel using ethyl acetate/heptane as eluant gave 0.33 g desired product, yield 74%.
