Reaction Steps
A suspension of 4-chloro-7-(trifluoromethyl)quinoline 1-A (158 mg, 0.68 mmol), 2-methyl-1H-indol-5-amine 1-B (100 mg, 0.68 mmol) and 4N HCl in dioxane (0.25 ml, 1.0 mmol) in a mix solvent (EtOH/dichloroethane, 1:1, 6 ml) was heated to 90° C. in a sealed tube overnight. The reaction mixture was concentrated and dissolved in 2 ml of DMSO. The solution was purified by HPLC (DionexSystem, 20-60% CH3CN/H2O over 30 minutes). 40 mg of N-(2-methyl-1H-indol-5-yl)-7-(trifluoromethyl)quinolin-4-amine 1 was obtained.
