95 °C

4-(2-Chloro-pyridin-3-yl)-pyrimidine (10.4 g, 54 mmol), 3-amino-4-methylbenzoic acid (19.4 g, 128 mmol), 17 g Et3N-TFA salt (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.), and 15 mL DMSO were mixed together in a sealed tube under argon. The mixture was stirred at 95° C. for 65 h. After cooling to RT, the residue was sonicated in 100 mL methanol to break up the solids, then filtered to obtain product as a yellow solid.
