Procedure

A mixture of 3-bromomethyl-6-(2,6-diethyl-phenyl)-4-methoxy-pyridine-2-carbonitrile (40 mg), K2CO3 (50 mg) and (S)-methyl-(1,2,3,4-tetrahydro-naphthalen-1-yl)-amine (40 mg) in CH3CN (2 mL) is stirred at room temperature overnight. Hexane (5 mL) and water (5 mL) are added to the mixture. The organic layer is separated, washed, once with brine, dried (Na2SO4), and concentrated. The crude is purified by PTLC (4:1 hexane/EtOAc) to give (S)-6-(2,6-diethyl-phenyl)-4-methoxy-3-{[methyl-(1,2,3,4-tetrahydro-naphthalen-1-yl)-amino]-methyl}-pyridine-2-carbonitrile. 1H NMR (CDCl3) 7.72 (d, 1H), 7.35 (t, 1H), 7.07-7.17 (m, 5H), 6.92 (s, 1H), 4.05 (m, 1H), 3.97 (d, 2H), 3.89 (s, 3H), 2.75 (m, 2H), 2.32 (m, 4H), 2.22 (s, 3H), 2.09 (m, 2H), 2.70-2.95 (m, 2H), 1.08 (t, 6H).
