Reaction Steps

To compound 12b, 4-(5-trifluoromethyl-[1,2,4]oxadiazol-3-yl)-benzoic acid, (40 mg, 0.155 mmol) in DMF (516 μL) was added TFFH (82 mg, 0.310 mmol), 2-methylpyridin-4-amine (33.5 mg, 0.310 mmol) and DIPEA (81 μL, 0.465 mmol). The reaction was stirred at 50° C. for 1.5 h. The reaction mixture was subjected to purification by reverse phase prep-HPLC (gradient elution, water/MeCN both containing 0.1% TFA). Fractions containing the desired compound were combined and freeze-dried. The resulting material was dissolved in a mix of ACN/MeOH. They were loaded on a PL-HCO3 MP cartridge (from StratoSpheres™ SPE) and eluted with ACN (3 ml). The eluate was diluted with water (10 ml) and freeze-dried to yield the final compound.
