Reaction Steps

To a mixture of N-[3-(1,2,3,4-tetrahydro-1-naphthylamino)propyl]phthalimide (569 mg, 1.7 mmol), potassium carbonate (709 mg, 5.1 mmol) and potassium iodide (280 mg, 1.7 mmol) in CH3CN (20 ml) was added 4-bromobutyronitrile (754 mg, 5.1 mmol). The mixture was refluxed under stirring for 18 h, and then filtered. The filtrate was concentrated under vacuum to dryness, and the residue was chromatographed on silica gel (eluting with 20% ethyl acetate/chloroform) to afford 4-[[(3-phthalimido)propyl](1,2,3,4-tetrahydro-1-naphthyl)amino]butyronitrile (336 mg, 50%): MS(ES+) m/e 402 [M+H]+; 1H NMR (400 MHz, CDCl3) δ 7.82 (dd, J=5.4, 2.9 Hz, 2H), 7.70 (m, 2H), 7.60 (d, J=7.6 Hz, 1H), 7.11 (m, 1H), 7.02 (m, 2H), 3.95 (m, 1H), 3.78 (m, 1H), 3.59 (m, 1H), 2.73 (m, 2H), 2.64 (m, 1H), 2.51 (m, 4H), 2.35 (m, 1H), 1.98 (m, 2H), 1.83 (m, 4H), 1.63 (m, 2H).
