Procedure

To a stirred solution of 1-(3-fluoro-2-methylphenyl)-1,6-dihydro-6-oxo-2-phenyl-5-pyrimidinecarboxylic acid (i.e. the product from Example 5, Step B) (41.0 g, 126 mmol) in dichloromethane (400 mL) was added oxalyl chloride (31.05 g, 252.0 mmol) at 0° C. followed by a catalytic amount (7 drops) of N,N-dimethylformamide. The reaction mixture was allowed to warm to room temperature and stir for 1 h. The reaction mixture was then concentrated under reduced pressure. To the resulting residue was added dichloromethane (400 mL), 1,3-cyclohexanedione (17.03 g, 152 mmol), followed by triethylamine (38.30 g, 379 mmol) and the reaction mixture was stirred at room temperature for 30 min. Saturated aqueous ammonium chloride solution was added, and the mixture was extracted with dichloromethane. The organic layer was washed once with water. Then the organic layer was dried (MgSO4) and concentrated under reduced pressure. The resulting solid was washed with chlorobutane to afford the title product pure as an off-white solid (37.6 g).
