Reaction Steps

(S)-3-(4-Cyano-3-fluoro-phenoxy)-2-methyl-propionic acid methyl ester (0.14 g) was shaken on a Parr shaker under 50 psi hydrogen for 16 h, using palladium hydroxide on carbon (0.01 g, 30% Pd by wt) in anhydrous methanol (20 mL) and concentrated hydrochloric acid (0.5 mL). The reaction mixture was filtered through sintered glass, and solvents removed in vacuo to afford 0.18 g of a white solid (95% yield).
