Procedure
Into a 8-dram vial, 5-Morpholin-4-yl-pyridin-2-ylamine (0.108 g, 0.604 mmol), N-[2-(2-Methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-N-methyl-methanesulfonamide (0.100 g, 0.274 mmol), Cesium fluoride (0.104 g, 0.686 mmol), N,N-Diisopropylethylamine (0.1051 mL, 0.6036 mmol) and tert-Butyl alcohol (1.50 mL) were added. The reaction was heated at 120° C. overnight. LCMS suggested presence of desired product. The solvent was removed under vacuum. The reaction mixture was purified via HPLC reverse phase chromatography with 0.1% TFA in Water and 0.1% TFA in ACN. The collected fractions were lyophilized to give a yellow solid (40 mg, 33%). LCMS (E/I+) 480.14 (M+H). NMR 1H (DMSO-d6)-10.49 (bs, 1H), 9.09 (s, 1H), 7.86-7.92 (m, 1H), 7.84 (bs, 1H), 7.70-7.80 (m, 1H), 7.66-7.73 (m, 1H), 7.50-7.64 (m, 3H), 7.13 (bs, 1H), 7.11 (bs, 1H), 3.75 (bs, 4H), 3.14 (s, 3H), 3.11 (bs, 4H), 2.83 (s, 3H).
