Reaction Steps

4-[5-(4-chloro-3-trifluoromethyl-phenylamino)-4H[1,2,4]triazol-3-yl]-phenol (127.8 mg, 0.36 mmol) was dissolved in 3 mL of anhydrous DMF in a 5 mL microwave vial (Personal Chemistry). Solid potassium bis(trimethylsilyl)amide (144.0 mg, 0.72 mmol) was added and the reaction mixture was stirred with heating at 80° C. for 15 min, then 3-bromopyridine (68.3 mg, 0.432 mmol) was added, followed by anhydrous K2CO3 (50.0 mg, 0.36 mmol). Then the vial was capped and microwaved at 250° C. for 30 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 (15.1 mg).
