실험 절차

To a solutiion of 6-bromo-benzo[cd]indol-2(1H)-one (1 g, 4 mmol) in N,N-dimethyl formamide was added K2CO3 (5.53 g, 40 mmol) and the resulting mixture was stirred for 0.5 hour under nitrogen. 4,4,4-trifluorobutyl iodide (915 mg, 4 mmol ) was next injected to the solution and the mixture was heated at 60° C. for 18 hours. The reaction media was next poured into 200 ml water and extracted with trichloromethane (3×100 ml). Column chromatography using gradient ethyl acetate in hexane (10˜20%) gave the desired product (1.225 g, 85%).
