実験手順

A stirred suspension of N-aminophthalimide (19.75 g), acetonylacetone (14.3 ml), p-toluenesulfonic acid (5mg), and toluene (406 ml) was heated at reflux for 1 hour and cooled to room temperature. The reaction mixture was combined with another reaction mixture and the entire mixture decolorized with activated charcoal. Filtration through a bed of celite gave a solution which upon partial concentration resulted in crystallization of the desired product as a solid (11.0 g), m.p. 182.5°-183.5° C.
