Reaction Steps

4-(trifluoromethyl)pyrimidine-2-carboxylic acid (500 mg, 2.6 mmol) was dissolved in a mixture of 1 mL of THF and 300 μL of MeOH and cooled to 0° C. Trimethylsilyldiazomethane (2M in ether, 2.6 mL, 5.2 mmol) was added dropwise. The solution was stirred for 2 hours at 0° C., then 1 hour at rt. A few drops of AcOH were added, followed by water. The aqueous solution was extracted three times with EtOAc. The combined organic layers were dried (Na2SO4), filtered, and concentrated to give an oil which was used without further purification. MS (ESI): mass calcd. for C7H5F3N2O2, 206.0; m/z found, 207.0 [M+H]+. 1H NMR (400 MHz, CDCl3) δ 9.24 (d, J=5.0 Hz, 1H), 7.87 (d, J=5.0 Hz, 1H), 4.10 (s, 3H).
