実験手順
The title compound was prepared from 5-(2-fluoro-phenyl)-cyclohexane-1,3-dione (1.03 g, 5.0 mmol), example 1/b stage 2, and N,N-dimethylformamide dimethylacetal (5 ml), following the procedure described for the synthesis of 5-(4-chloro-phenyl)-2-dimethylaminomethylene-cyclohexane-1,3-dione (example 2/a stage 1) except that the reaction was stirred at 100° C. for 16 h.
