4-Methyl-[2,2]bipyrimidinyl-5-carboxylic acid (0.5 g, 2.31 mmol) is combined with 5-fluoro-3-methyl-indol-1-yl-ammonium chloride (464 mg, 2.31 mmol), N-methylmorpholine (233 mg, 2.31 mmol) and DMF (10 mL). The suspension is stirred for 5 minutes at rt, then 4-(4,6-dimethoxy-[1,3,5]triazin-2-yl)-4-methyl-morpholin-4-ium chloride is added (640 mg, 2.31 mmol). The reaction is heated to 50° C. for 4 h. The reaction is then poured into water (50 mL), the suspension is chilled for 2 h in the refrigerator, and then filtered. The solids are then suspended in acetonitrile at 50° C. for 4 h, cooled, then filtered to afford 4-methyl-[2,2′]bipyrimidinyl-5-carboxylic acid (5-fluoro-3-methyl-indol-1-yl)-amide (60%). MS: 363 (M+H); 1H NMR (300 MHz, CDCl3): δ=2.27 (s, 3H), 2.77 (s, 3H), 7.07 (dt, 1H), 7.36 (dd, 1H), 7.38 (s, 1H), 7.44-7.48 (m, 1H), 7.70 (t, 1H), 9.05 (d, 2H), 9.29 (s, 1H), 11.9 (s, 1H). IC50=4.5 nM.
