Reaction Steps

Dissolve N-[4-(4-aminophenoxy)-2-pyridyl]cyclopropanecarboxamide (186 mg, 0.69 mmol), tert-butyl 3-[3-(phenoxycarbonylamino)-5-(trifluoromethyl)phenoxy]azetidine-1-carboxylate (312 mg, 0.69 mmol) and DMAP (17 mg, 0.14 mmol) in DMF (10 mL), stir at 100° C. for 16 hrs. Cool the reaction, pour the mixture to water (50 mL), adjust pH=7 with saturated NaHCO3 solution, extract with EtOAc (15 mL×3). Combine the organic layers, wash with brine (100 mL), dry over anhydrous Na2SO4. Concentrate under reduced pressure to give the crude product. Purification by chromatography (silica gel, EtOAc:PE=1:1) affords the target compound (300 mg, 69%). MS: (M+1): 628.3.
