3.10 g (12.3 mmol) of diethyl[2-(2-methyl-4-nitrophenoxy)ethyl]amine is dissolved in 250 mL of ethyl acetate, 0.55 g of Raney nickel is added, and the mixture is hydrogenated for 36 hours at 50 psi and ambient temperature. The catalyst is filtered off and the filtrate is evaporated down in vacuo. Yield: 2.70 g (99% of theory); C13H22N2O (M=222.33); calc.: molecular ion peak (M+H)+: 223; found: molecular ion peak (M+H)+: 223; Rf value: 0.35 (silica gel, dichloromethane/methanol (9:1)).
