Procedure

3-[5-(4-chloro-3-trifluoromethyl-phenylamino)-4H[1,2,4]triazol-3-yl]-phenol (100 mg, 0.282 mmol) was dissolved in 2 mL of anhydrous DMF in a 5 mL microwave vial. Solid potassium bis(trimethylsilyl)amide (140.6 rug, 0.705 mmol) was added and the reaction mixture was stirred with heating at 80° C. for 15 min, then 4-chloro-pyridine hydrochloride (46.5 mg, 0.31 mmol) was added, followed by anhydrous K2CO3 (19.5 rug, 0.141 mmol). Then the vial was capped and microwaved at 250° C. for 20 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 (34.6 mg of beige solid).
