実験手順

3.0 g (8.33 mmol) of ethyl 3-[2-(2-(t-butoxycarbonylamino)ethoxy)-4-cyanophenyl]acrylate was dissolved in a mixture of 20 ml of 4 N solution of hydrogen chloride in dioxane and 10 ml of dioxane. The obtained solution was stirred at room temperature for 4 hours. The solvent was evaporated and the residue was dissolved in 50 ml of DMF. 2.22 g (9.17 mmol) of 1-(4-pyridyl)-4-piperidinecarboxyic acid hydrochloride, 4.27 g (9.17 mmol) of bromotripyrrolidinophosphonium hexafluorophosphate and 3.48 ml (25.0 mmol) of triethylamine were added to the obtained solution, and they were stirred at room temperature for 3 days. The solvent was evaporated, and the obtained crude product was purified by the silica gel column chromatography to obtain the title compound.
