A mixture of ethyl iodide (0.1M), 1-phenylaminonaphthalene (0.05M), KOH (0.1M) and copper bronze (1 g) was stirred for 31/2 hours in N-methylpyrrolidone (20 cm3) at 120° C. under an atmosphere of nitrogen. The mixture was cooled, poured into water (2 liters) and extracted with CH2Cl2 (3×300 cm3). The combined extracts were washed with water, dried over MgSO4 and the CH2Cl2 solvent removed in vacuo to give 229 g (98% yield) of 1-(N-phenyl-N-ethylamino)naphthalene as a yellow liquid.
