Tetrahydrofuran → (R)-1-(2-nitro-4-(trifluoromethyl)phenyl)piperidin-3-ol

Participants

Reaction Steps

To a 100-mL round bottom flask (RBF) was added (R)-piperidin-3-ol hydrochloride (1.29 g, 9.37 mmol), sodium bicarbonate (2.76 g, 32.8 mmol), THF and 1-fluoro-2-nitro-4-(trifluoromethyl)benzene (1.31 ml, 9.37 mmol). The yellow mixture was heated to 75° C. with a water-cooled reflux condensor and allowed to stir 14 h. The reaction was filtered through a glass frit, rinsing with EtOAc, and concentrated in vacuo to give (R)-1-(2-nitro-4-(trifluoromethyl)phenyl)piperidin-3-ol as an orange oil.
