3-[3-fluoro-4-(trifluoromethyl)phenyl]prop-2-enoic Acid → 3-[3-Fluoro-4-(trifluoromethyl)phenyl]propionic acid

Participants

Reaction Steps

10% NIX was added to a stirred solution of 3-(3-fluoro-4-(trifluoromethyl)phenyl)-acrylic acid (I-77a: 5.5 g, 0.0234 mol) in methanol. The resulting mixture was stirred under hydrogen atmosphere for 4 hours. The reaction was monitored by TLC (5% methanol in CHCl3). The catalyst was filtered through celite bed and the solvent distilled under reduced pressure to afford the crude product. Purification by column chromatography on silica gel (2% methanol in CHCl3) afforded 4.5 g of the product (81.8% yield).
