실험 절차

To a mixture of N,N-bis-(2-chloroethyl)benzylamine (Szarvasi, E., Eur. J. Med. Chem. Chim. Ther. 11(2), 115-124, 1976) (60 g, 22 mmol), 2-pyridylacetonitrile (2.51 mL, 22 mmol) and tetrabutylammonium hydrogen sulfate (0.26 g, 0.7 mmol) in toluene (10 mL), sodium hydroxide solution (2.43 g in 4.86 mL H2O) was added over a 20 minute period. The reaction mixture was heated at 65° C. for 4 hours. The reaction mixture was cooled to room temperature, 10 mL of water was added and the solution partitioned between ethyl acetate (45 mL) and water. The organic layer was dried over sodium sulfate, filtered and concentrated. Purification of the crude product by column chromatography (hexane:EtOAc, 2:3) gave 6.2 g (87%) of the title compound as a red solid; 1H-NMR (CDCl3): δ2.05 (d, J=13.1 Hz, 2H), 2.30 (t, J=13.2 Hz, 2H), 2.48 (t, J=13.2 Hz, 2 H), 2.97 (d, J=12.1 Hz, 2 H), 3.57 (s, 2 H), 7.19-7.27 (m, 6 H), 7.30 (d, J=7.6 Hz, 1 H), 7.60 (t, J=7.6 Hz, 1 H ), 8.58 (d, J=4.6 Hz, 1 H).
