A mixture of 2-(2-chloro-phenyl)-4-ethyl-oxazole-5-carboxylic acid 2,5-dioxo-pyrrolidin-1-yl ester (174 mg, 0.5 mmol) and 6-morpholin-4-yl-pyridin-3-ylamine (90 mg, 0.5 mmol) in 5 mL of acetonitrile was stirred at 85° C. overnight. The solvent was removed in vacuo, and the crude product was purified by flash chromatography (Merck silica gel 60, 230-400 mesh, 0-15% methanol in methylene chloride for 30 min) to yield 2-(2-chloro-phenyl)-4-ethyl-oxazole-5-carboxylic acid (6-morpholin-4-yl-pyridin-3-yl)-amide (107 mg, 52% yield) as a light yellow solid. LCMS calcd for C21H21ClN4O3 (m/e) 412, obsd 413 (M+H).
