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

实验步骤: 2.2 g (9.82 mmoles) of 2-undecyl-2-imidazoline and 1.4 g (16.3 mmoles) of methyl acrylate were dissolved in 50 ml of methylene chloride and the solution was heated to reflux. The reaction was followed by glc. The solution was concentrated and the residue was distilled at 160°-170° C./0.1 mm to give 2.2 g (72.4%) of product. the solution was heated to reflux The solution was concentrated the residue was distilled at 160°-170° C./0.1 mm

反应条件: temp:125.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 18.32 g (100 mmoles) of undecyl cyanide, 8.5 ml (127 mmole) of ethylenediamine and 0.5 ml of carbon disulfide were mixed and heated in an oil bath at 125° C. for 24 hours. The reaction mixture was cooled, treated with dilute hydrochloric acid and treated with charcoal. The light yellow filtrate was basified and extracted with ethyl acetate, the organic extracts dried over magnesium sulfate and concentrated. The residue was Kugelrohr distilled and then recrystallized from toluene. Yield 13.7 g (61.1%), m.p. 82° C. The reaction mixture was cooled extracted with ethyl acetate the organic extracts dried over magnesium sulfate concentrated distilled recrystallized from toluene
