反応手順
A mixture of 44.4 g (0.28 mole) trichloroacetamidine, 32.0 g (0.28 mole) methylacetoacetate, 37.5 g (0.28 mole) potassium carbonate, and 450 ml water was stirred for 3 days. A trace of solid was removed by filtration and the filtrate was made acidic with hydrochloric acid. The product precipitated out to give 28.9 g (46% yield; mp 173°-174° C.). The structure was confirmed via mp*, infrared and elemental analysis.
