Reaktionsschritte
To a solution of ethyl isonipecotate (3.00 g, 19.1 mmol) in THF (20 mL) and MeOH (20 mL) was added 3,3,3-trifluoropropionaldehyde (2.14 g, 19.1 mmol) and AcOH (1.09 mL, 19.1 mmol) followed by sodium cyanoborohydride (1.20 g, 19.1 mmol). The reaction was allowed to stir for 10 min., at which time the reaction was quenched with water (15 mL) then made basic with NaHCO3 and extracted with EtOAc. The organic layer was washed with brine, dried and concentrated in vacuo to yield a white powder (3.3 g, 68%). Mass Spectrum: Calcd for C11H19NF3O2(M+H): 254. Found: 254.
