Versuchsvorschrift

2-Phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid [4-(piperidin-3-yloxy)-phenyl]-amide (46.2 mg, 0.107 mmol), 4,4-dimethyl-dihydro-pyran-2,6-dione (18.3 mg, 0.128 mmol) and triethylamine (30 uL, 0.214 mmol) in 1 mL DMSO were treated as above. The crude product was purified by flash chromatography to yield 3,3-dimethyl-5-oxo-5-(3-{4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenoxy}-piperidin-1-yl)-pentanoic acid as a white solid (34 mg, 55%). ES-MS calcd for C29H30F3N3O6 (m/e) 573.57, obsd 574 (M+H).
