1-Iodopropane → N-Propyl-N-[2-[4-(4,4,4-trifluoro-3,3-dimethoxybut-1-yl)phenoxy]ethyl]dodecylamine

Participants

Reaction Steps

A solution of N-[2-[4-(3,3-dimethoxy-4,4,4-trifluorobut-1-yl)phenoxy]ethyl]dodecylamine (500 mg, 1.05 mmol), diisopropyl ethylamine (0.35 ml, 2.1 mmol) and 1-iodopropane (0.26 ml, 2.66 mmol) in isopropanol was heated to reflux for 21 h. After cooling to r.t., the mixture was diluted with ethyl acetate and filtered. The filtrate was concentrated in vacuo, and the residue was chromatographed on silica gel (dichloromethane/methanol 98:2 to 95:5) to afford the title compound (0.526 g, 73%) as a colorless oil.
