実験手順

Preparation of 2-hexyl-N-N'-dimethyl-N,N'-dibutyl-propane diamide of formula: ##STR27## 0.1 mol of N,N'-dimethyl-N,N'-dibutyl-propane diamide dissolved in 400 ml of tetrahydrofuran are introduced into a one liter reactor, scavenged by a nitrogen stream. Cooling takes place to -50° C. using an acetone bath and solid carbon dioxide and pouring takes place of a solution of n-butyl lithium prepared from 0.1 mol of n-butyl lithium in 100 ml of anhydrous tetrahydrofuran. Under the same conditions is poured a solution of hexyl iodide prepared from 0.1 mol of hexyl iodide and 100 ml of anhydrous tetrahydrofuran. When pouring is at an end, the temperature is allowed to rise to ambient temperature again, followed by refluxing the tetrahydrofuran for three hours. Cooling is allowed to take place, followed by hydrolysis with a water-ethanol mixture. The tetrahydrofuran is expelled and in this way a precipitate is formed. This is taken up with methylene chloride, followed by washing with water, drying the organic layer, expelling the solvent and then distillation. The boiling point is 145° to 148° C. under 0.4 mm of mercury and the product is a yellow liquid. Its characterization by nuclear magnetic resonance of the proton and by potentiometric dosage confirms that it corresponds to the above formula.
