Versuchsvorschrift
Into a 50-mL round-bottom flask, was placed ethyl (2Z)-3-[4-methoxy-3,5-bis(trifluoromethyl)phenyl]prop-2-enoate (280 mg, 0.82 mmol, 1.00 equiv), Palladium carbon (0.28 g), methanol (10 mL). The mixture was subjected to 2 atm of H2 and stirred overnight at 25° C. The reaction progress was monitored by LCMS. The solids were filtered out. The resulting mixture was concentrated under vacuum. This resulted in 0.28 g (99%) of ethyl 3-[4-methoxy-3,5-bis(trifluoromethyl)phenyl]propanoate as yellow oil. Mass spectrum (ESI, m/z): Calcd. for C14H14F6O3, 345.1 (M+H). found 345.1.
