Participants

Reaction Steps

4-(2-Chloro-pyridin-3-yl)-pyrimidine (240 mg, 1.2 mmol), 3-amino-4-fluorobenzoic acid (217 mg, 1.40 mmol), and 340 mg Et3N-TFA salt were mixed together in a sealed tube under argon. (The liquid Et3N-TFA reagent was generated by adding 2.5 mL TFA dropwise to a 0° C. solution of 3 mL Et3N in isopropanol, then concentrating by rotary evaporator followed by 30 minutes under high vacuum.). The mixture was melted at 95° C., and heating was continued overnight. The residue was triturated with a small amount of methanol and filtered to obtain the title compound as a solid. MS m/z=311 [M+H]+. Calc'd for C16H11FN4O2: 310.29.
