Reaction Steps

4-[5-(4-trifluoromethoxy-phenylamino)-4H[1,2,4]triazol-3-yl]-phenol (112.0 mg, 0.33 mmol) was dissolved in 2 mL of anhydrous DMF in a 5 mL microwave vial (Personal Chemistry). Solid potassium bis(trimethylsilyl)amide (132.8 mg, 0.66 mmol) was added and the reaction mixture was stirred with heating at 80° C. for 15 min, then 4-chloro-2,6-diamino-pyrimidine (53.0 mg, 0.366 mmol) was added, followed by anhydrous K2CO3 (46.0 mg, 0.33 mmol). Then the vial was capped and microwaved at 250° 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 (51.1 mg of beige solid).
