反应详情

The methylisocyanate (220 mg, 3.9 mmol) was added to a solution of 3-(octahydroindolizin-7-yl)-5-amino-1H-indole (500 mg, 1.95 mmol) in 10 ml of dimethylformamide. The reaction was allowed to stir for 72 hours. TLC indicated the reaction was complete so the reaction was concentrated to give a purple gum. This material was chromatographed on a short FLORISIL™ column using 20% methanol in methylene chloride (ammonium hydroxide) as solvent to give 340 mg of a white foam. The white foam was recrystallized from methanol/ethyl acetate to give 165 mg of product. (27.1%).
