Procedure

To a solution of 4-(4-cyano-2-(2,6-difluorophenyl)oxazol-5-ylamino)benzoic acid (0.020 g, 0.059 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.022 g, 0.059 mmol), and diisopropylethylamine (0.020 mL, 0.117 mmol) in N,N-dimethylformide (2 mL) was added morpholine (0.005 mL, 0.059 mmol) and the reaction mixture stirred at room temperature for 16 hours. The reaction was then diluted with EtOAc washed with 1M HCl, water and brine. The organic phase was dried over MgSO4 and the solvent removed in vacuo. The residue was purified by preparative HPLC to afford 2-(2,6-difluorophenyl)-5-(4-(morpholine-4-carbonyl)phenylamino)oxazole-4-carbonitrile (0.009 g, 0.022 mmol, 37%) as a yellow solid. LCMS (2) Rt: 2.38 min; m/z (ES+) 411.
