Procedure

Neat pyridin-3-amine (79 mg, 0.84 mmol) was added in one charge to a stirred solution of 5-bromo-2-{[(4-fluorophenyl)methyl]oxy}benzoic acid (may be prepared as described in Description 87; 200 mg, 0.56 mmol), EDC (213 mg, 1.11 mmol) and HOBT (170 mg, 1.11 mmol) in DMF (3 ml) at room temperature. The reaction mixture was stirred at 25° C. overnight. Water (25 ml) was added and the solid was filtered, washed with water (15 ml), and dried in vacuo. The residue was further purified with Prep-TLC (eluate: dichloromethane:methanol=25:1) to yield the title compound as a white solid. 76 mg.
