Procedure

A mixture of 4-(benzyloxy)aniline (1010 mg), DIEA (1.771 mL) and methyl 2-fluoro-4-(trifluoromethyl)pyridine-3-carboxylate (1130 mg) in NMP (10 mL) was stirred at 150° C. for 2 h and at 200° C. for 1 h under microwave irradiation. The mixture was poured into water, and the mixture was extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography (silica gel, EtOAc/hexane) to give the title compound (225 mg).
