Reaction Conditions

Reaction Steps

A mixture of 2-chloro-pyrimidine-4-carboxylic acid (2.0 g, 13 mmol), 4-trifluoromethyl phenyl boronic acid (2.4 g, 13 mmol), tetrakis(triphenylphosphine)palladium(0) (0.7 g, 0.6 mmol), potassium phosphate (5.3 g, 25 mmol), 1,2-dimethoxyethane (40 mL) and water (8 mL) was heated to 80° C. under a blanket of nitrogen in a sealed tube. After 5 h, the mixture was partitioned between water (50 mL) and ethyl acetate (50 mL). The aqueous layer was extracted with ethyl acetate (2×50 mL). The combined organic layers were discarded, and the aqueous layer was acidified with concentrated HCl to pH 2. The aqueous layer was extracted with ethyl acetate (2×50 mL). The combined organic layers were dried (MgSO4), filtered, and concentrated. The residue was purified directly by FCC to afford a white solid (1.4 g, 42%). MS (ESI): mass calcd. for C12H7F3N2O2, 268.0 m/z found, 269.0 [M+H]+.
