Participants

Reaction Steps

Racemic (3R,4S) and (3S,4R)-1-Methyl-3-nitro-4-(2-(trifluoromethyl)phenyl)-pyrrolidine (296.8 mg, 1.082 mmol) was dissolved in MeOH (5 mL) and Acetic Acid (5 mL) then zinc (354 mg, 5.41 mmol) was added at 0° C. The reaction mixture was warmed to room temperature and stirred under nitrogen overnight. The suspension was filtered over celite and washed with methanol. The filtrate was concentrated in vacuo and the residue was suspended in ethyl acetate, cooled in an ice bath, and basified with conc. NH4OH. The organic phase was separated and washed with brine. The organic layers were combined and dried over sodium sulfate, filtered, and concentrated in vacuo to give racemic (3R,4S) and (3S,4R)-1-methyl-4-(2-(trifluoromethyl)phenyl)pyrrolidin-3-amine (230.9 mg, 0.945 mmol, 87%), which was carried onto the next step without further purification. MS ESI calc'd. For C12H15F3N2 [M+1]+ 245, found 245.
