Procedure

To a solution of 5-(4-(4-(tert-butoxycarbonyl)piperazin-1-yl)phenyl)-2-(1H-indol-4-yl)oxazole-4-carboxylic acid potassium salt (0.045, 0.09 mmol) in DCM (0.9 ml) and DMF (0.7 ml) was added hydroxybenzotriazole monohydrate (0.018 g, 0.12 mmol), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.027 g, 0.14 mmol) and 0.5M ammonia in dioxane (0.9 ml, 0.45 mmol) and the resultant mixture stirred overnight at room temperature. The solvent was then removed in vacuo and the residue purified by preparative HPLC to afford tert-butyl 4-(4-(4-carbamoyl-2-(1H-indol-4-yl)oxazol-5-yl)phenyl)piperazine-1-carboxylate (0.027 g, 0.06 mmol, 65%). LCMS (2) Rt: 3.33 min; m/z (ES+) 488.
