The reaction was stirred at RT for 1 h, diluted with EtOAc (50 ml) and washed with 1 N HCl twice. The aqueous layer was basified with NaHCO3, extracted with EtOAc twice and washed with H2O and brine. The organic layer was dried over Na2SO4 and evaporated to give {2-[4-(tert-butyl)-2-nitrophenoxy]ethyl}-dimethylamine. It was hydrogenated under H2 atmosphere to give {2-[4-(tert-butyl)-2-aminophenoxy]ethyl}-dimethylamine.
