実験手順
Dissolved 4-[10,11-dihydro-5-(2-propenyl)-5H-dibenzo[a,d]cyclohepten-5-yl]-1-methyl-1,2,5,6-tetrahydropyridine (3.3 g, 10.0 mmol) in 50 mL of benzene, and added 2,2,2-trichloroethylchloroformate (3.0 mL, 4.6 g, 21.8 mmol). Refluxed for 20 hours under a nitrogen atmosphere. Cooled to room temperature, and added water. Extracted with ether. Dried combined organic extracts with MgSO4, filtered, and evaporated. Purified crude product by flash chromatography on silica gel eluting with dichloromethane. Combined appropriate fractions, and evaporated to give 3.7 g (75% yield) of 2,2,2-trichloroethyl 4-[10,11-dihydro-5-(2-propenyl)-5H-dibenzo[a,d]cyclohepten-5-yl]-1,2,5,6-tetrahydro-pyridinecarboxylate as an oil.
