17 EXAMPLE 17; Synthesis of 1-Naphthylethylamine

Gaseous hydrogen chloride was bubbled through a stirred solution of N-diphenylphosphinyl-1-naphthylethylamine in ethyl alcohol for 2 hours at room temperature. The reaction mixture was concentrated, made basic by the addition of an aqueous solution of sodium hydroxide (2 M) and extracted with dichloromethane (3×10 ml). The organic layer was washed with brine (1×10 ml), dried over magnesium sulphate and concentrated to give the product as a yellow liquid in 80% yield.
