Procedure

To a solution of 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (100 mg, 0.39 mmol) in methylene chloride (15 mL) was added 6-(4-pyrimidin-2-yl-piperazin-1-yl)-pyridin-3-ylamine (100 mg, 0.39 mmol) and diisopropylethylamine (0.35 mL, 1.90 mmol). To this solution was added bromo-tris-pyrrolidino-phosphoniumhexafluorophosphate (PyBrOP) in one portion (280 mg, 0.59 mmol). The mixture was stirred at room temperature overnight. The residue was purified by HPLC to yield 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid [6-(4-pyrimidin-2-yl-piperazin-1-yl)-pyridin-3-yl]-amide as a light yellow powder. The NMR spectrum obtained on the sample is compatible with its structure. LCMS calcd for C24H20F3N7O2 (m/e) 495, obsd 496 (M+H).
