Procedure

A mixture of 1.79 g (5.09 mmol) of 6-(2-{[(2-methylphenyl)amino]methyl}-1-naphthyl)pyridine-2-carbaldehyde, 1.85 g (25.4 mmol) of tert-butylamine and 0.641 g (10.2 mmol) of NaBH3CN in 100 ml of dry ethanol was stirred overnight at room temperature. The resulting mixture was evaporated to dryness. The product was isolated from the residue by flash chromatography on neutral alumina (eluent: dichloromethane, then dichloromethane-ether=1:1, vol.). Yield 1.10 g (53%) of yellowish oil. Anal. calc. for C28H31N3: C, 82.11; H, 7.63; N, 10.26. Found: C, 82.34; H, 7.79; N, 10.11. 1H NMR (CDCl3): 7.90 (d, J=8.6 Hz, 1H, 4-H in naphthyl), 7.88 (m, 1H, 8-H in naphthyl), 7.79 (m, 1H, 4-H in Py), 7.65 (d, J=8.6 Hz, 1H, 3-H in naphthyl), 7.38-7.48 (m, 4H, 3-H in Py and 5,6,7-H in naphthyl), 7.32 (m, 1H, 5-H in Py), 7.01-7.04 (m, 2H, 3,5-H in ortho-tolyl), 6.63 (m, 1H, 4-H in ortho-tolyl), 6.52 (m, 1H, 6-H in ortho-tolyl), 4.22 (m, 2H, Naph-CH2N), 4.01 (m, 2H, Py-CH2N), 3.50 (br. s, 2H, NH), 2.11 (s, 3H, Me in ortho-tolyl), 1.18 (s, 9H, tBu).
