Reaction Steps

4-[5-(4-trifluoromethoxy-phenylamino)-4H[1,2,4]triazol-3-yl]-phenol (66.4 mg, 0,197 mmol) was dissolved in 2 mL of anhydrous DMF in a 5 mL microwave vial (Personal Chemistry). Solid potassium bis(trimethylsilyl)amide (39.4 mg, 0.197 mmol) was added and the reaction mixture was stirred with heating at 80° C. for 15 min, then 4-chloro-2-pyridinecarboxamide (33.7 mg, 0.197 mmol) was added, followed by anhydrous K2CO3 (27.3 mg, 0.197 mmol). Then the vial was capped and microwaved at 200° C. for 15 min. Then the reaction mixture was diluted with ca. 1 mL of MeOH, filtered through 0.22 um syringe filter and purified by reverse-phase preparative HPLC in acetonitrile/water system with 0.01% TFA. The product was isolated as a TFA salt (46.6 mg).
