Reaction Steps
30 gm (0.103M) ethyl-o-nitrophenylacetylacetoacetate was added over a period of 15-20 minutes to a saturated ammoniacal ethanol solution (prepared by bubbling NH3 gas into 400 cc. absolute for 15-20 minutes while cooling the solution to 0°-5° C.). The orangy mixture was stirred for 1 hour at 5°-10° C. and then left in the refrigerator overnight. The ethyl-γ-2-nitrophenylacetoacetate crystals formed were filtered and dried in vacuum. Additional solid was obtained after evaporation of the filtrate and washing with water to remove any amide formed.
