실험 절차

To a mixture of ethyl 7-bromo-3-(3-hydroxypropyl)-1H-indole-2-carboxylate (EXAMPLE 1C) (100 mg), 6-aminonaphthalen-1-ol (98 mg) and triphenylphosphine, polymer supported (204 mg 0.613 mmol) in tetrahydrofuran (4 ml) was added di-tert-butyl diazene-1,2-dicarboxylate (141 mg). The reaction mixture was stirred at room temperature for 3 hours. The insoluble material was filtered off and the filtrate was concentrated. The residue was purified by flash chromatography (ethyl acetate in hexanes) to provide the title compound.
