1-{3-[1-(3-Fluorophenyl)methylidene]piperidin-1-yl}ethanone → 1-[3-(3-Fluorobenzyl)piperidin-1-yl]ethanone

Participants

Reaction Steps

A mixture of 1-{3-[1-(3-fluorophenyl)methylidene]piperidin-1-yl}ethanone (Intermediate 225, 0.7 g), palladium hydroxide (20% on carbon, 0.07 g) in ethyl acetate (20 mL) and IMS (1 mL) was degassed by nitrogen/vacuum purging. The mixture was stirred under an atmosphere of hydrogen for 21.5 hours. The mixture was filtered the filtrate was evaporated to dryness to give 1-[3-(3-fluorobenzyl)piperidin-1-yl]ethanone (0.66 g).
