2N HCl(aq) (0.42 mL, 833 μmol) was added to a stirred mixture of 4-(2-fluoropyridin-3-yl)-6-methyl-1,3,5-triazin-2-amine (171 mg, 833 μmol) and 1H-indol-4-amine (132 mg, 1000 μmol) in 1,4-dioxane (4.00 mL, 46762 μmol) and the brown mixture was heated at 100° C. overnight. After cooling, the reaction mixture was concentrated and the crude residue was dissolved in DCM/MeOH and mixed with SiO2. The solvent was evaporated and the residue was purified by flash column chromatography (pure DCM to 5% MeOH in DCM) followed by washing the eluent concentrates with EtOAc to give N-(3-(4-amino-6-methyl-1,3,5-triazin-2-yl)pyridin-2-yl)-1H-indol-4-amine (58 mg, 22%) as a yellow solid.
