Procedure

A solution of 3-(2-Chloropyridin-4-yloxy)-4-fluorobenzoic acid (2.22 g, 8.29 mmol), 2-fluoro-5-methylaniline (1.56 g, 12.4 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 3.78 g, 9.95 mmol) and N-methylmorpholine (2.00 mL, 18.2 mmol) in dimethylformamide (22 mL) was heated at 90° C. for 2 h. The solvent was evaporated in vacuo at 50° C. To the residue was added water resulting in a thick oil. The water was decanted and the oil dissolved in EtOAc then extracted twice with water, 1M hydrochloric acid and brine. The organic layer was dried (MgSO4), filtered and evaporated to crude 6 (3.37 g). Trituration with dichloromethane (25 mL) gave 3-(2-Chloropyridin-4-yloxy)-4-fluoro-N-(2-fluoro-5-methylphenyl)benzamide as white solid.
