实验步骤: A mixture of 5-hydroxy-1H-indole-2-carboxylic acid ethyl ester (2 g, 10 mmol), 2-bromo-1-pyrrolidin-1-yl-ethanone (3 g, 20 mmol) and cesium carbonate (19.5 g, 60 mmol) in dimethylformamide (16 mL) was stirred at room temperature for 24 hours. The reaction was diluted with ethyl acetate (150 mL), washed with water (5×50 mL) and brine, dried and concentrated. The residue was recrystallized from ethyl acetate and hexane to give 0.8 g (25%) 5-(2-oxo-2-pyrrolidin-1-yl-ethoxy)-1H-indole-2-carboxylic acid ethyl ester as a brown solid. washed with water (5×50 mL) and brine dried concentrated The residue was recrystallized from ethyl acetate and hexane

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of pyrrolidine (1.7 g, 24 mmol), bromoacetyl bromide (4.6 g, 24 mmol) and triethylamine (2.02 g, 20 mmol) in dichloromethane (40 mL) was stirred at room temperature for 4 hours. The precipitate was filtered off and the residue was concentrated to give 3.1 g of 2-bromo-1-pyrrolidin-1-yl-ethanone as a light brown solid. The precipitate was filtered off the residue was concentrated
