実験手順
A mixture of 5.0 g. (0.0282 mole) of 1,2,5,6-tetrahydro-3-pyridinecarboxylic acid methyl ester, hydrochloride, 8.08 g. (0.282 mole) of 4,4-diphenyl-3-butenyl bromide and 10 g. of crushed potassium carbonate was refluxed in 200 ml. of acetone for 15 hours. The reaction mixture was evaporated, extracted into ethyl acetate from water, dried, evaporated and chromatographed on silica (dry column) eluted with hexane/hexane:ethyl acetate to give 1,2,5,6-tetrahydro-1-(4,4-diphenyl-3-butenyl)-3-pyridinecarboxylic acid methyl ester hydrochloride.
