In the second step, 4-acryloylaminobenzoic acid ethyl ester (200 mg, 0.91 mmol), 1,5,6,7-tetrahydro-4H-indol-4-one (123 mg, 0.91 mmol) and potassium carbonate (126 mg, 0.91 mmol) were combined in dry N,N-dimethylformamide (3 mL) and stirred at room temperature for 24 hours, then heated to 60 C for 6 hours. Water (20 mL) was added and the resulting precipitate was vacuum filtered washing with water. The isolated solid was dried under vacuum to yield 180 mg (56%) of the title compound.
