tert-butyl 3-[4-(aminomethyl)phenyl]propanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To 223 mg of tert-butyl (2E)-3-(4-cyanophenyl)acrylate were added 12 mL of methanol, 5 ml of THF, 1 ml of an acetic acid solution, and 90 mg of 10% palladium-carbon in this order, followed by stirring for 3 hours under hydrogen at 3 atm. The catalyst was removed by filtration and the filtrate was concentrated under reduced pressure. To the residue were added a saturated aqueous sodium hydrogen carbonate solution and ethyl acetate to carry out a layer separation operation. The organic layer was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure to obtain 177 mg of tert-butyl 3-[4-(aminomethyl)phenyl]propanoate. The catalyst was removed by filtration the filtrate was concentrated under reduced pressure To the residue were added a saturated aqueous sodium hydrogen carbonate solution and ethyl acetate a layer separation operation The organic layer was dried over anhydrous sodium sulfate the solvent was evaporated under reduced pressure
