2-butyl-2-phenylhexanenitrile → β,β-Dibutylbenzeneethanamine

Participants

Reaction Steps

α,α-Dibutyl-benzeneacetonitrile ((2), 7.0 gm; 0.0237 mol) is dissolved in borane-THF complex (1.1 equiv.) at room temperature for 18 hours. Once reaction is complete, ethanol (50 ml) is added, and the reaction is evaporated to dryness. Once dry, the residue is suspended in 100 ml 1M HCl, and the suspension is evaporated to dryness on a rotary evaporator. This procedure is repeated three times. After the final evaporation, the white residue is dissolved in 1M NaOH (100 ml), and extracted with diethyl ether (2×150 ml). The extracts are combined, dried with Na2SO4, filtered and evaporated to dryness to yield 1-amino-2,2-dibutyl-2-phenylethane (3), wt=6.4 gm (90%).
