A solution of 4-(phenylamino)benzoic acid (0.048 g, 0.225 mmol), 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.052 g; 0.225 mmol), HATU (0.094 g; 0.247 mmol) and N,N-diisopropylethylamine (0.097 mL; 0.563 mmol) in DMF (5 mL), was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and sodium hydrogen sulphate, the organic layer was washed with sodium carbonate, brine, dried and concentrated in vacuo. The crude mixture was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) to yield 0.024 g (27%) of the title compound as a yellow solid.
