Reaction Conditions

Reaction Steps

A suspension of (E)-tert-butyl 2-cyano-3-(3,4-dichlorophenyl)acrylate (1.05 g, 3.52 mmol) and zinc (3.45 g, 52.8 mmol) in AcOH (20 ml) was allowed to stir at 100° C. After stirred for 1 hour, the reaction mixture was cooled to ambient temperature, and diluted with toluene and brine. The phases were separated, and the organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to give tert-butyl 2-cyano-3-(3,4-dichlorophenyl)propanoate (819 mg); Retention time=1.41 minutes (condition B); MS (ES+)=317.0 (m+18).
