81 mg (0.29 mmol) of 3-oxo-2-[(9-oxo-9H-fluoren-4-yl)methylene]butanenitrile are dissolved with 50 mg (0.29 mmol) of 6-isopropoxypyrimidine-2,4-diamine in 5 ml of isopropanol and heated under reflux under argon for 6 h. The suspension is cooled and then filtered with suction, and the remaining solid is washed with isopropanol. 74 mg (59% of theory) of the title compound are obtained as a white solid.
