Reaction Steps

To a mixture of 2-(3-(trifluoromethoxy)phenyl)quinoline-8-carboxylic acid (1 gram, 3.3 mmol) and HATU (1.71 g, 4.5 mmol) in DMF (30 mL) was added 3-aminopyridine (423 mg, 4.5 mmol) followed by DIPEA (1.03 mL, 6 mmol). The mixture was stirred 18 hours, water (150 mL) was added and the resulting precipitate was collected by filtration. The crude material was purified by chromatography (silica gel, gradient 0 to 100% Ethyl acetate in Pentane), the desired fraction was concentrated and the product recrystallized from methanol to obtain the product as a white solid (550 mg, 45% yield).
