실험 절차

13.9 g. (0.1 mole) of N-methyl-N-[1-methyl-2-(2-furyl)-ethyl] amine are dissolved in 80 ml. of dioxane, whereupon 6 g. of paraformaldehyde and 1 g. of cuprous chloride are added and gaseous acetylene is introduced into the solution at 80° C. under stirring for 30 hours. The reaction mixture is filtered and the filtrate is evaporated. The residue is dissolved in benzene, the benzene solution is washed with water, dried over potassium carbonate and evaporated. The residue is distilled off in vacuo. Thus 6.8 g. of N-methyl-N-[1-methyl-2-(2-furyl)-ethyl]-propynyl amine are obtained. Bp.: 114°-116° C./20 Hgmm; nD20 =1.4910.
