Participants

Reaction Steps

(±)-2-(4-Cyano-3-fluoro-phenoxy)-propionic acid tert-butyl ester (1.77 g, 6.7 mmol) was shaken on a Parr shaker under 40 psi hydrogen for 30 min, using palladium hydroxide on carbon (1 g, 30% Pd by wt) in 200 mL anhydrous methanol. The reaction mixture was filtered through sintered glass, and solvents removed in vacuo to afford 1.71 g colorless oil (95% yield).
