実験手順

To a solution of tert-butyl (3R)-3-({3-chloro-5-[(1Z)-3-ethoxy-2-fluoro-3-oxo-1-propen-1-yl]-2-pyridinyl}amino)-1-piperidinecarboxylate (3.3 g) in EtOH (19.3 ml) was added solution of 4N HCl in dioxane (19.3 ml) at ambient temperature and the mixture was stirred at same temperature for 1.5 hr. Diisopropylether was added to the mixture and precipitate was collected by filtration to give ethyl (2Z)-3-{5-chloro-6-[(3R)-3-piperidinylamino]-3-pyridinyl}-2-fluoroacrylate dihydrochloride (2.98 g).
