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

实验步骤: To a solution of 1H-indazole-3-carboxylic acid (0.745 g, 4.6 mmol) in 20 mL dimethylformamide, was added 1,1'-carbonyldiimidazole (0.745 g, 4.6 mmol). This mixture was stirred at room temperature for 4 h, and to it was added dropwise a solution of 1-(4-aminobutyl)piperidine (0.718 g, 4.6 mmol) dissolved in 3 mL dimethylformamide. This solution was then stirred at room temperature for 18 h, the volatiles were evaporated and the residue was diluted with water. Extraction with ethyl acetate followed by water and brine washes gave 1.40 g of an oil which was sufficiently pure for use in the next reaction. Mass spectrum, m+ =301. This solution was then stirred at room temperature for 18 h the volatiles were evaporated the residue was diluted with water Extraction with ethyl acetate
