실험 절차

To a solution of 5-(4-(4-(tert-butoxycarbonyl)piperazin-1-yl)phenyl)-2-(pyridin-3-ylamino)oxazole-4-carboxylic acid (0.046 g, 0.1 mmol) in DMF (1 ml) was added O-7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.065 g, 0.17 mmol), diisopropylethylamine (0.03 ml, 0.17 mmol) and 0.5M NH3 in dioxane (0.6 ml, 0.3 mmol) and the resultant mixture stirred at room temperature overnight. A further portion of O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.020 g, 0.05 mmol), diisopropylethylamine (0.01 ml, 0.056 mmol) and 0.5M NH3 in dioxane (0.2 ml, 0.1 mmol) was added and the reaction stirred for 1 hour. The solvent was removed in vacuo and the residue purified by preparative HPLC to afford tent-butyl 4-(4-(4-carbamoyl-2-(pyridin-3-ylamino)oxazol-5-yl)phenyl)piperazine-1-carboxylate (0.006 g, 0.013 mmol, 13%). LCMS (2) Rt: 2.64 min; m/z (ES+) 465.
