5-Aminoisoquinoline (0.50 g, 3.47 mmol) and 3-[4-(trifluoromethyl)phenyl]acrylic acid (3.47 mmol) were combined in a sealed tube and heated at 175° C. for 16 hours with stirring. The mixture was cooled to room temperature, diluted with MeOH, transferred to a flask, and concentrated under reduced pressure. The residue was triturated with ethyl acetate and filtered to provide the title compound.
