Versuchsvorschrift
The title compound was prepared from 5-p-tolyl-cyclohexane-1,3-dione (1.0 g, 4.85 mmol), example 1/c, and N,N-dimethylformamide dimethylacetal (5 ml), following the procedure described for 5-(4-chloro-phenyl)-2-dimethylaminomethylene-cyclohexane-1,3-dione (example 2/a stage 1) except that the reaction was stirred at ambient temperature for 16 h.
