反応手順
A mixture of 30.0 g (0.18 mole) trichloroacetamidine, 25.2 g (0.18 mole) potassium carbonate, 30.3 g (0.18 mole) ethyl-4-chloroacetoacetate and 400 ml water was stirred 18 hours. The aqueous solution was filtered and acidified with hydrochloric acid to give a precipitate. The precipitate was washed and dried to give 17.0 g (36% yield) of crude product. An analytical sample recrystallized from ligroin had mp 138°-144° C. The structure was confirmed via infrared and elemental analysis.
