Sodium Hydroxide → (Z)-2-(4-chloro-2-fluoro-phenyl)-5,5-dimethyl-hex-2-enenitrile

Participants

Reaction Steps

To a solution of 4-chloro-2-fluoro-benzyl cyanide (Oakwood) (1.70 g, 10.0 mmol) and 3,3-dimethyl-butyraldehyde (Aldrich) (1.0 g, 10.0 mmol) in iPrOH (20 mL) was added 2 N NaOH (2.0 mL) dropwise at rt and the reaction mixture was stirred at rt overnight. The reaction mixture was diluted with EtOAc and the organic layer was separated, washed with water, brine, dried over Na2SO4 and concentrated. The residue was dried overnight in vacuum to give (Z)-2-(4-chloro-2-fluoro-phenyl)-5,5-dimethyl-hex-2-enenitrile (2.52 g, 100%) as a colorless oil which was used in the next step without further purification.
