Neat HOBT (90 mg, 0.59 mmol) was added in one charge to a stirred solution of 2-[(phenylmethyl)oxy]-5-(1-piperidinylcarbonyl)benzoic acid (may be prepared as described in Description 53; 200 mg, 0.59 mmol), 3-pyridinamine (55.5 mg, 0.59 mmol), and EDC (113 mg, 0.59 mmol) in N,N-dimethylformamide (5 ml) under nitrogen at room temperature. The reaction mixture was stirred at room temperature for 4 h. The mixture was diluted with water (50 ml). The precipitate was collected by filtration, washed with ether (5 ml), and dried to yield the title compound as a white solid. 65 mg.
