To a stirred solution of (6-chloro-5-propyl-pyrimidin-4-ylmethyl)-(3-methyl-butyl)-amine (0.715 g, 2.8 mmol) and 6-fluoro-pyridine-2-carboxylic acid (0.47 g, 3.34 mmol) in DCM (10 ml) is added EDCI (0.61 g) and DMAP (0.153 g). The mixture is stirred at room temperature overnight. DCM (10 ml) is added to dilute the mixture. The mixture is washed with water (5 mL), dried (Na2SO4) and solvent evaporated. Preparative TLC purification of the residue (2:1 of hexane: ethyl acetate) provides the title product. H1 NMR δ (CDCl3) 8.69 and 8.75 (s, 1H), 7.71-7.97 (m,1H), 7.58-60 (m, 1H), 4.79 and 5.07 (s, 2H), 3.50-3.64 (m, 21), 2.59-2.87 (m, 2H), 1.45-1.72 (m,5H), 0.92-1.09 (m, 4H), 0.81 (d, 6H).
