Reaction Steps
A mixture of 2,5-dimethylindole (765 mg) and 4-chloro-8-trifluoromethylquinoline (1.22 g) in NMP (1.5 ml) and 4M HCl in dioxane (0.2 ml) was heated at 140° C. for 1 h. After cooling the mixture was triturated with ether and filtered to give the sub-title compound (1.33 g) as a dark red solid.
