Borane;tetrahydrofuran → 2-(2-Bromo-4-fluorophenyl)-2-methylpropan-1-amine

Participants

Reaction Steps

Add borane-THF complex (2 M in THF, 10 mL, 20 mmol) to a stirred solution of 2-(2-bromo-4-fluoro-phenyl)-2-methyl-propionitrile (0.8 g, 3.30 mmol) in 10 mL of THF at 0° C. Stir the mixture at 0° C. to RT over the weekend. Quench the reaction with diluted ammonium hydroxide. Extract the product with chloroform. Dry the organic phase over sodium sulfate and concentrate to give the title compound (0.8 g, 99%). MS (ES) m/z 246/248 [M+1]+.
