N,N,4-三甲基哌嗪-1-乙胺

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

实验步骤: To a solution of zinc (II) chloride in tetrahydrofuran(0.5M, 300 mL, 150 mmol) was added dropwise 1-[2-(dimethylamino)ethyl]-4-methylpiperazine (38.54 g, 225 mmol) below 20° C. under nitrogen atmosphere. The slurry was stirred at room temperature for 4 hrs., and filtered under nitrogen flow. The cake was washed with dry tetrahydrofuran(100 mL), and dried at room temperature under reduced pressure overnight. The title compound (47.56 g, quantitative yield) was obtained as colorless crystals. mp: ca. 260° C.(dec.). IR(KBr, cm−1): 3,430; 2,960; 2,870; 2,820; 1,490; 1,330; 1,190; 1,140; 1,040; 990; 860 , and filtered under nitrogen flow The cake was washed with dry tetrahydrofuran(100 mL) dried at room temperature under reduced pressure overnight
