Procedure

Diisopropylazadicarboxylate (1.19 mL) was added dropwise to a solution of triphenylphosphine (1585 mg), 4-(2-aminopyridin-3-yl)phenol (750 mg) and (3-fluorophenyl)methanol (0.434 mL) in THF (dry) (15 mL) at room temperature and the mixture was stirred overnight and concentrated in vacuo. The residue was purified by column chromatography (1st; NH-silica gel, eluted with EtOAc in hexane, 2nd; silica gel, eluted with EtOAc in hexane) to give the title compound (210 mg) as a white powder.
