Participants

Reaction Steps

Phenyl-t-butylamine (6 g, 0.04 mol) was treated with conc.HCl (5 ml) and a solution of NaNO2(6.4 g, 2.4 eq.) in 20 ml of water was added slowly. The resulting mixture was stirred for 2 hr at r.t. to produce an oily layer which was extracted with EtOAc, washed with brine, and dried over Na2SO4.Yield 6 g (85%). This nitrosoamine was used for the next step without further purification.
