Reaktionsschritte

Into a 1-neck round-bottom flask was added 4-methylpyridin-3-amine (1.02 g, 0.00940 mol) and 2-chloro-N,N-diethylnicotinamide (2.00 g, 0.00940 mol) in 1,4-dioxane (20 mL), and then sodium hydride (0.94 g, 0.024 mol) was added. The reaction was heated at reflux for 1 hour. The mixture was allowed to cool and water was added. The mixture was then extracted with ethyl acetate 3× and the combined organic extracts were washed with water, brine, dried over MgSO4, and concentrate in vacuo. Upon cooling, the product crystallized. The crystalline solid was filtered off, washed with ether and dried to give 2.27 g of the desired product. 1H NMR (300 MHz, CDCl3): δ 9.15 (s, 1H), 8.21-8.24 (m, 2H), 7.90 (br s, 1H), 7.47 (dd, 1H J1=7.5, J2=1.8 Hz), 7.11 (d, 1H, J=4.8 Hz), 6.75 (dd, 1H, J1=7.5, J2=5.1 Hz), 3.46-3.51 (m, 4H), 2.29 (s, 3H), 1.25 (t, 6H). MS [M+1]=285.
