This compound was prepared in a manner analogous to Step E, Example 1. Here, 8.2 grams (0.0206 mole) of methyl 6-chloro-2-methyl-3-[6-trifluoromethyl-2,4(1H,3H)-pyrimidinedion-3-yl]benzoate was combined with 5.7 grams (0.410 mole) of potassium carbonate and 4.4 grams (0.309 mole) of methyl iodide in 200 mL of THF. The reaction product was purified by column chromatography on silica gel using mixtures of EtOAc and hexane as eluants. The fractions containing product were combined and concentrated under reduced pressure, yielding 7.8 grams of subject compound. The NMR spectrum was consistent with the proposed structure.
