C1(C[N:8]2[CH2:12][CH2:11][CH:10]([CH2:13][NH:14][CH2:15][C:16]([F:19])([F:18])[F:17])[CH2:9]2)C=CC=CC=1.[H][H]>[Pd].CO>[F:19][C:16]([F:17])([F:18])[CH2:15][NH:14][CH2:13][CH:10]1[CH2:11][CH2:12][NH:8][CH2:9]1A mixture of 7.15 g (26.3 mmole) 1-(phenylmethyl)-N-(2,2,2-trifluoroethyl)-3-pyrrolidinemethanamine 100 ml of methanol and 0.7 g of 20% palladium on carbon was shaken in an atmosphere of hydrogen at about 4.5×105Pa and at room temperature for 24 hours. The catalyst was filtered and the filtrate evaporated under reduced pressure. The residue was distilled under vacuum (63°-65° C., 2.8 mm Hg) to give 2.55 g of N-(2,2,2-trifluoroethyl)-3-pyrrolidinemethanamine.
