실험 절차

A mixture of 4-(piperazin-1-yl)-9-((2-(trimethylsilyl)ethoxy)methyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carbonitrile (100 mg, 0.2 mmol), (S)-2-(1-(tert-butoxycarbonyl)pyrrolidin-2-yl)acetic acid (220 mg, 1.0 mmol), 1-hydroxybenzotriazole (50 mg, 0.4 mmol), (3-dimethylamino-propyl)-ethyl-carbodiimide hydrogen chloride (70 mg, 0.4 mmol), and triethylamine (0.1 mL, 0.7 mmol) in methylene chloride (2.5 mL) was stirred at ambient temperature overnight. The reaction mixture was diluted with methylene chloride (50 mL) and washed with saturated aqueous sodium bicarbonate solution (20 mL). The organic layer was separated, dried over sodium sulfate, filtered, concentrated in vacuo, and purified flash chromatography (silica, 4 g, ISCO, 0-70% ethyl acetate in heptane) to afford the title compound as a white foam, which was used in the next step without any further purification (140 mg).
