実験手順
3-bromo-1,1,1-trifluoropropane (5.5 ml, 51.65 mmol) in dioxane (50 ml) in the presence of potassium carbonate (14.15 g, 102.5 mmol) was reacted with ethanolamine (3.0 ml, 51 mmol) at 60° C. for 36 hours. The solvent was evaporated and the residue purified by chromatography on silica gel. Elution with dichloromethane:methanol (95:5) then increased polarity to dichloromethane:methanolic ammonia (95:5) yielded 2-((3,3,3-trifluoropropyl)amino)ethanol (4.47 g, 55% yield):
