Participants

Reaction Steps

To a solution of etythro 1-(2-trifluoromethylphenyl)-2-nitro-butan-1-ol (0.18 g, 0.00068 mole) in THF (5 mL) and methanol (5 mL) was added 10% palladium on carbon (50 mg) followed by ammonium formate (0.21 g, 5 equivalents). The resulting mixture was stirred at room temperature for 1.5 hour then diluted with Et2O, filtered and evaporated in vacuo. Flash column chromatography (SiO2, 2% MeOH in CHCl3) gave erythro 1-(2-trifluoromethylphenyl)-2-amino-butan-1-ol. (0.074 g, 47%), and some starting material (0.035 g).
