Reaction Steps

5 g (20 mmol) of (4-bromo-2-tert-butylphenyl)-ethylamine are dissolved, under a stream of nitrogen, in 200 ml of DMSO. After cooling to 0° C., 1.7 g (43 mmol) of sodium hydride are added slowly. After 30 minutes, 3.4 ml (43 mmol) of iodoethane are added and the mixture is then brought back to ambient temperature and stirred for an entire weekend. It is then poured into a saturated solution of ammonium chloride and extracted twice with diethyl ether. The organic phase is washed with water and then dried and concentrated to dryness. The residue is purified by flash chromatography (95/5 heptane/EtOAc). 3.6 g of (4-bromo-2-tert-butylphenyl)diethylamine are obtained in the form of a yellow oil (yield=63%).
