실험 절차

To a solution of 4-fluoroaniline (1 g, 9 mmol) in DCM (20 mL) at room temperature was added isobutyraldehyde (985 μL, 10.8 mmol) followed by portionwise sodium triacetoxyborohydride (2.86 g, 13.5 mmol) and the reaction was stirred at room temperature for 64 hours. The reaction was concentrated and then dissolved in DCM and MeOH, dry loaded onto silica then purified by silica gel column chromatography (0-25% DCM in cyclohexane) to give (4-fluoro-phenyl)-isobutyl-amine (817 mg, 54%). LCMS (m/z, Method A) ES+ 168 [M+1]+.
