実験手順: N-(n-propyl) ethanolamine 2,4,6-trichlorophenylether, 11.3 gm, was added to 100 ml of methylene chloride. 5.6 ml of triethylamine was added to the system. The system was stirred at about -70° C for 5 minutes and then 3.5 ml of α-bromoacetyl bromide was added dropwise. The system was stirred at room temperature for an additional 18 hours. The reaction was stopped and the system poured into 100 ml of water. The product was extracted with methylene chloride. The organic solution was dried over magnesium sulfate and the methylene chloride was then removed by stripping to give the N-(α-bromoacetyl), N-(npropyl) ethanolamine 2,4,6-trichlorophenylether as a brown oil. Listed as Compound No. 3 in Table I. The system was stirred at room temperature for an additional 18 hours The product was extracted with methylene chloride The organic solution was dried over magnesium sulfate the methylene chloride was then removed

実験手順: N-(n-propyl)-2,4,6-trichlorophenoxyacetamide, 44.0 gm, was added to 250 ml of toluene. 28 ml of borane methyl sulfide [BH3 (CH3)2S](2 equivalents) was then slowly added to the system. The system was heated at approximately 60° C. for 15 hours at which time reaction completion was checked by IR spectroscopy. 200 ml of methanol was then slowly added to the system.

実験手順: A solution of sodium hydroxide (7.8 g, 0.195 mol) in water (20 ml) was added to a solution of 2,4,6-trichlorophenol (38.0 g, 0.192 mol) in ethanol (200 ml). 1,2-dibromoethane (47 g, 0.25 mol) was then added and the resultant mixture was refluxed overnight. On cooling, the solid was filtered off and the filtrate concentrated under reduced pressure. Ether was added to the residue and the solution was then washed with dilute sodium hydroxide solution and dried over anhydrous magnesium sulphate. After removal of the solvent by evaporation, the residue was recrystallised from ethanol to give 1-bromo-2-(2,4,6-trichlorophenoxy)ethane as a white solid (39.4 g). A mixture of the 1-bromo-2-(2,4,6-trichlorophenoxy) ethane (20.0 g, 0.066 mol), triethylamine (6.7 g, 0.066 mol) and propylamine (3.9 g, 0.066 mol) in ethanol (500 ml) was then refluxed overnight. After removal of the solvent by evaporation, the residue was dissolved in ether, washed with water and dried (MgSO4). Evaporation of the solvent left an oil which, after flash chromatography on silica gel using chloroform as the eluant, yielded N-propyl-N-2-(2,4,6-trichlorophenoxy)ethylamine as an oil (12.6 g). was then refluxed overnight After removal of the solvent by evaporation the residue was dissolved in ether washed with water dried (MgSO4) Evaporation of the solvent left an oil which
