실험 절차

To 2-(3,5-difluorophenyl)-1,6-dihydro-1-(2-methoxyethyl)-6-oxo-5-pyrimidinecarboxylic acid (i.e. the product from Example 9, Step D) (0.25 g, 0.81 mmol) in 10 mL of dichloromethane was added oxalyl chloride (0.21 g, 1.6 mmol) and one drop of N,N-dimethylformamide. The reaction mixture was stirred at room temperature for 2 h and then concentrated under reduced pressure. The remaining crude oil was re-dissolved in dichloromethane (10 mL) and then treated with bicyclo[3.2.1]octane-2,4-dione (0.12 g, 0.88 mmol) (prepared according to U.S. Pat. No. 6,815,563) and triethylamine (0.16 g, 1.6 mmol). After 30 min at room temperature, a catalytic amount of 2-hydroxy-2-methyl-propanenitrile (0.0075 g, 0.088 mmol) and triethylamine (0.16 g, 1.6 mmol) were added and the reaction mixture was stirred at ambient temperature over night. The reaction mixture was then concentrated under reduced pressure and purified by medium pressure liquid chromatography on silica gel eluting with 0 to 10% methanol in chloroform to provide 0.180 g of the title compound (also known as 3-[[2-(3,5-difluorophenyl)-1,6-dihydro-1-(2-methoxyethyl)-6-oxo-5-pyrimidinyl]carbonyl]biciclo[3.2.1]octane-2,4-dione), a compound of the present invention, as a solid.
