実験手順
A mixture of 2.15 g. of 4-(p-fluorophenyl)-1,2,3,6-tetrahydropyridine hydrochloride, 2.5 g. of p-(2-bromoethoxy)-nitrobenzene, 2.8 g. of potassium carbonate, 20 ml. of ethanol and 2 ml. of water is refluxed for 3 days. After filtration the crude product crystallizes from the hot reaction mixture. It is purified by chromatography on silica gel using methylene chloride for elution. The 4-(p-fluorophenyl)-1,2,3,6-tetrahydro-1-[2-(p-nitrophenoxy)ethyl]pyridine obtained melts at 104°-107° after recrystallization from ethanol.
