After completion of the reaction, the reaction mixture was quenched with 3% aq NaOH solution, the precipitate obtained was filtered, the filtrate was collected was concentrated under reduced pressure to get a residue. The residue was diluted with ethyl acetate, the organic layer was washed with brine solution and dried over sodium sulfate. The organic layer was concentrated under reduced pressure to afford 85 mg (91.39% Yield) of biphenyl-4-yl-methyl-amine.
