Procedure

A mixture of anhydrous potassium carbonate (10 gm, in excess) and cyclohexylamine (0.29 ml, 0.003 mole) was taken in dry DMSO (40 ml). Now 3-(2-naphthyloxy)-1-chloropropane (0.5 gm, 0.002 mole) was added in it. Reaction mixture was refluxed at 140° C. for 7 hrs and the reaction was completed as checked by TLC. Reaction mixture was poured in distilled water (60 ml) and extracted with ethyl acetate thrice. The organic layer was separated and concentrated to get oily compound which was later crystallized by benzene hexane to get N-cyclohexyl-[3-(naphthalen-2-yloxy)-propyl]amine, solid. m.p. 98° C. (yield 0.61 gm, 88%).
