Reaction Steps
The product from Example 45A (0.11 g, 1 mmol), 3-bromo-4-fluorobenzaldehyde (0.2 g, 1 mmol), and 1,3-cyclopentanedione (0.1 g, 1 mmol) in ethyl alcohol (2 mL) were heated at 80° C. for 2 days in a sealed tube. The reaction mixture was allowed to cool to ambient temperature and was evaporated under reduced pressure. The residue was chromatographed eluting with 19:0.5:0.5 ethylacetate:formic acid:water to provide the title compound (0.07 g).
