Procedure

2-Phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (4-piperidin-4-yl-phenyl)-amide (50.7 mg, 0.122 mmol), (1H-tetrazol-5-yl)-acetic acid (15.6 mg, 0.122 mmol), triethylamine (51 uL, 0.366 mmol) and BOP (54 mg, 0.128 mmol) in 1 mL DMF were reacted as above to give a clear oil. The crude product was crystallized from methanol/acetonitrile to yield 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid {4-[1-(2-1H-tetrazol-5-yl-acetyl)-piperidin-4-yl]-phenyl}-amide as off-white crystals (11 mg, 17%). ES-MS calcd for C25H22F3N7O3 (m/e) 525.49, obsd 526 (M+H).
